A cartridge includes a developing roller rotatable about an axis Lof the developing roller and a coupling member for receiving a driving force, with the coupling member being operatively connected to the developing roller. A first urging member is contactable to the coupling member, with the first urging member being configured to urge the coupling member in a first direction. A second urging member is contactable to the coupling member, with the second urging member being configured to urge the coupling member in a second direction that is opposite to the first direction. The first and second urging members are simultaneously contactable to the coupling member.

Cartridge and electrophotographic image forming apparatus

Disclosed is a cartridge attachable to an image forming apparatus body, the cartridge including: a memory member storing information relating to the cartridge; and a supporting body having a memory mounting portion on which the memory member is mounted, the memory member having a first surface, a second surface, and a lateral surface, the first surface is provided with a contact portion connected to a body electrode portion of the body of the image forming apparatus when the cartridge is installed in the body of the image forming apparatus, the memory mounting portion has a first opposing portion opposing the second surface and a second opposing portion opposing the lateral surface when the memory member is mounted, the memory member is mounted by adhesive between the second surface and the first opposing portion and between the lateral surface and the second opposing portion.

Cartridge including a memory mounting portion and image forming apparatus including the cartridge

A cartridge includes a photosensitive drum rotatable about an axis extending in an axial direction; a memory including a storing element configured to store information, a memory contact electrically connected to the storing element, and a substrate having a surface on which the memory contact is provided; and a frame which supports the photosensitive drum, on which the substrate is mounted, and which includes a first end with respect to the axial direction and a second end opposite from the first end. The frame includes a container provided with an accommodating chamber for accommodating a developer collected from the photosensitive drum and with an opening communicating with the accommodating chamber and includes a mounting member mounted on the container so as to cover the opening. The mounting member includes a supporting portion for supporting the substrate.

Cartridge, toner cartridge, and image forming apparatus

A process cartridge includes a photosensitive drum and a developing roller for developing a latent image on the photosensitive drum. The process cartridge also includes a protrusion having a surface configured to receive a force to move a frame supporting the developing roller from the first position in which the developing roller contacts the photosensitive drum to the second position in which the developing roller is spaced apart from the photosensitive drum. The process cartridge is configured such that, when the frame is in the first position and the process cartridge is oriented with the photosensitive drum and the protrusion positioned at a bottom side of the process cartridge, (i) a rotational axis of the photosensitive drum is lower than a rotational axis of the developing roller, and (ii) as viewed in a direction of the rotational axis of the photosensitive drum, the surface of the protrusion extends in a direction that is perpendicular to a part of a surface at the bottom side of the process cartridge that extends away from the photosensitive drum and away from the protrusion.

Image forming apparatus and process cartridge including protrusion to receive a force for moving developing roller

According to a first aspect of the present invention, there is provided a toner cartridge detachably mountable to a receiving device, the toner cartridge comprising a container including a accommodating portion for accommodating the toner and a discharge opening for discharging the toner from the accommodating portion into the receiving device; and an open/close member including a closing portion for closing the discharge opening and an engaging portion movable relative to the closing portion, the open/close member being rotatable relative to the container between (a) an opening position for causing the closing portion to open the discharge opening and (b) a closing position for causing the closing portion to close the discharge opening, wherein the engaging portion is movable relative to the closing portion between (c) a engaging position for engagement with the receiving device to receive a force for moving the open/close member from the opening position to the closing position when the toner cartridge is dismounted from the receiving device and (d) a retracted position retracted from the engaging position, and wherein the engaging portion is movable from the retracted position to the engaging position with rotation of the open/close member from the closing position to the opening position.

Toner cartridge, toner supplying mechanism and shutter

A cartridge for an image forming apparatus includes: a process unit to be used to form an image; a first member including a first resin material; a second member including a second resin material having higher flame retardant capability than the first resin material; and an electrode member including a contact section configured to be supplied with power from an apparatus main body of the image forming apparatus. The electrode member is configured to electrically connect the apparatus main body to the process unit. The second resin material of the second member has a greater density than the first resin material of the first member. The contact section is located in the vicinity of the first and second members and is closer to the second member than to the first member.

Process unit including first and second resin materials and image forming apparatus

An electrophotographic image forming apparatus includes a main assembly and a cartridge mountable to the main assembly, with the cartridge being movable in the main assembly between a developing position at a terminal end of a mounting path and a spaced position moved from the developing position in a direction different from a direction of the mounting path. The cartridge includes a developer carrying member and a coupling member capable of inclining relative to a rotational axis of the developer carrying member. The coupling member is capable of taking a reference position when the cartridge is at a developing position, an at-dismounting position inclined relative to the rotational axis of the developer carrying member when the cartridge is dismounted from the main assembly, and an at-spaced position inclined relative to the rotational axis of the developer carrying member in a direction different from that in the at-dismounting position.

Process cartridge for image forming apparatus

An image forming apparatus includes a mounting portion for mounting a process cartridge, the process cartridge including a first unit having an image bearing drum, and a second unit having a developing roller, the second unit being movable between a contact position in which the roller contacts the drum and a spaced position in which they are mutually spaced; an engageable member engageable with a force receiving portion provided on the second unit; wherein the engageable member is movable between a first position for maintaining the second unit in the spaced position by engaging with the force receiving portion, a second position for permitting movement of the second unit from the spaced position to the contact position; and a third position for permitting the process cartridge to be mounted, by being pressed by the process cartridge to retract, when the process cartridge is mounted to the mounting portion.

Process cartridge having a protrusion with a surface configured to receive a force to move a frame of the process cartridge

A cartridge includes a projection portion provided in a first region of an upper surface of a frame in a vertical direction. The projection portion projects more upward than second regions between which the first region is interposed. An inside of the projection portion is a space that is part of a developer accommodating portion. The projection portion is configured to pass through a space under an abutting portion while being elastically deformed by the abutted portion being pressed by the abutting portion after the cartridge is transitioned from the first posture to the second posture in accordance with movement of the cartridge in the attaching direction.
