The first sheet metal includes a first facing surface and a first rear surface. The second sheet metal is fixed to the first sheet metal at a fixing portion and includes a second facing surface facing the first facing surface and a second rear surface. The first sheet metal is deformed in a first direction from the first rear surface toward the first facing surface in such a manner that the fixing portion is formed. The fixing portion includes a projection projecting from the second rear surface in the first direction. The moving member overlaps the fixing portion and is disposed at a position that is on an opposite side of the first rear surface from the projection and faces the first rear surface in the first direction.

An image forming apparatus includes an apparatus body, a sheet storage portion, and an air blowing portion disposed within the apparatus body. The apparatus body includes a body portion oriented toward an upstream side in an attaching direction of the sheet storage portion, the body portion including an air intake port, and a cover member provided to be openable and closable with respect to the body portion. The sheet storage portion includes a storage portion body and a storage portion cover. In a state where the cover member is closed with respect to the body portion and the sheet storage portion is attached to the apparatus body, the air intake port is disposed to be overlapped with the cover member and the storage portion cover when viewed in the attaching direction and is covered by the cover member and the storage portion cover.

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 an aspect of the present disclosure, an image forming apparatus includes a feeding module, an image forming module, and a fixing module. The feeding module feeds a recording material. The image forming module includes a photosensitive drum and forms a developer image on the recording material fed to the image forming module by the feeding module. The fixing module fixes the developer image formed by the image forming module to the recording material. The image forming module includes a scanner frame that supports an exposure unit configured to expose the photosensitive drum. The feeding module is installed on the scanner frame.

A cartridge includes a photosensitive drum and a developing roller configured to develop an electrostatic latent image formed on the photosensitive drum. A first frame rotatably supports the photosensitive drum and a second frame rotatably supports the developing roller. A movable member is movable with respect to the second frame, with the movable member including a first force receiving surface and a second force receiving surface. The second frame is movable relative to the first frame between a contact position in which the developing roller is in contact with the photosensitive drum and a spaced position in which the developing roller is spaced from the photosensitive drum. The second force receiving surface is capable of being moved by the first force receiving surface between a first position and a second position, and the second frame is capable of being moved by the second force receiving surface from the contact position toward the spaced position.

Process cartridge and image forming apparatus

A cartridge includes a container, a light guide including incident and emergent portions, and a cover including outer and inner surfaces. When a direction directing from the outer surface toward the inner surface is a first direction, and a direction in which the incident and emergent portions are arranged is a second direction, (i) the outer surface is recessed toward a downstream side of the first direction between the incident and emergent portions, (ii) a first end of a bottom of the recessed portion on an incident portion side is positioned on a side downstream with respect to the first direction, of a second end of the bottom on an emergent portion side, and (iii) the bottom is curved so as to be recessed toward the downstream side of the first direction between the first and second ends relative to an imaginary rectilinear line connecting these ends.

Cartridge and image forming apparatus

An image forming apparatus to form an image on a recording material includes a photosensitive member, an exposure device to form a latent image on the photosensitive member, a tubular body defining a space in which at least a part of the exposure device is contained, and a support portion that supports the exposure device and is provided along a rotation axis direction of the photosensitive member in the space of the tubular body. The image forming apparatus further includes, in the rotation axis direction, a first side plate fixed to one end portion of the tubular body, and a second side plate fixed to another end portion of the tubular body. One support portion end portion in the rotation axis direction is fixed to the first side plate, and another support portion end portion in the rotation axis direction is fixed to the second side plate.

Image forming apparatus with improved vibration rigidity

A process cartridge is detachably mountable to a main assembly of an electrophotographic image forming apparatus. The cartridge includes an electrophotographic photosensitive drum, a developing roller, a drum unit containing the drum, a developing unit containing the roller and being movable so the roller contacts and is spaced from the drum, and a first force receiver receiving a force from a main-assembly first force applier by movement of a door from open to closed positions when mounting the cartridge and a second force receiver movable from a stand-by position by movement of the first force receiver by a force received from the first force applier. The second force receiver takes a projected position receiving a force from the second force applier to move the developing unit so the roller moves out of contact with the drum, the projected position being higher than the stand-by position.

Image forming apparatus having feeding and fixing modules provided on a transfer frame

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.
