A multilayer ceramic electronic device includes a multilayer chip having a plurality of dielectric layers and a plurality of internal electrode layers facing each other through each of the plurality of dielectric layers, an external electrode that is provided on an end face of the multilayer chip in a second direction orthogonal to a first direction in which the plurality of internal electrode layers face each other, and has a plurality of glass portions that are spaced from each other on a surface of the external electrode, and a plated layer that is provided on the external electrode and has discontinuous portions on the plurality of glass portions.

Multilayer ceramic electronic device

A cartridge that can be inserted in an apparatus main body of an image forming apparatus by moving along an axial direction of an image bearing member includes the image bearing member, a frame configured to support the image bearing member, a storage member configured to store therein information on the cartridge, and include an electrical contact, and a first pressed section and a second pressed portion configured to be pressed by the apparatus main body. The electrical contact is disposed between the first pressed section and the second pressed section, and is configured to be in contact with the main body contact on a lower side in a state where the cartridge is attached to the apparatus main body.

Cartridge, process cartridge, and image forming apparatus

A cartridge including: a first unit including an image bearing member and a first portion, and configured to take a removal posture when the cartridge is to be removed from a main body; a second unit including a developer bearing member and a second portion, the second unit being movable between a first position where the developer bearing member is in contact with the image bearing member and a second position where the developer bearing member is separated from the image bearing member and where the second portion is in contact with the first portion, wherein when the first unit takes the removal posture, the second unit is located at the second position, and when the second unit is located at the second position, movement of the second unit in a direction, in which the developer bearing member is separated from the image bearing member, is restricted.

Cartridge including photosensitive drum and developing roller that can be easily separated

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

A method of manufacturing a coil for a torque sensor includes: holding a bobbin with a jig, the bobbin being formed in a cylindrical shape and provided with first inclined grooves and second inclined grooves on a cylindrical outer peripheral surface of the bobbin, the first inclined grooves being inclined at a preset specified angle with respect to an axial direction of the cylindrical shape, and the second inclined grooves being inclined at the specified angle with respect to the axial direction in a direction opposite to the first inclined grooves; and rotating the bobbin while simultaneously supplying insulated wires from nozzles arranged to surround the bobbin, and driving the nozzles in a direction orthogonal to a rotation direction of the bobbin so as to wind the insulated wires around the bobbin along the first inclined grooves or the second inclined grooves.

Cartridge and image forming apparatus

A process cartridge includes a photosensitive drum and a first casing rotatably supporting the photosensitive drum. The process cartridge also includes a developing roller configured to develop an electrostatic latent image formed on the photosensitive drum with toner, a supplying roller configured to supply the developing roller with the toner, and a second casing rotatably supporting the developing roller and the supplying roller and containing the toner. A rotatable coupling is provided with a projection and operatively connected to the supplying roller and the developing roller so that the coupling can transmit a rotational force to the supplying roller and the developing roller, and at least a part of the coupling being movable in a direction perpendicular to a rotational axis of the coupling. Rotatable gears are configured to transmit the rotational force from the coupling to the developing roller, and a spring urges the at least part of the coupling toward the first casing in the direction perpendicular to the rotational axis of the coupling.

Process cartridge and image forming apparatus

In a remanufacturing method for remanufacturing a cartridge from a material cartridge, the material cartridge is attachable to and detachable from an apparatus main body of an image forming apparatus, and the apparatus main body includes a guide member. The material cartridge includes a frame member including an engagement portion configured to be engaged with the guide member, and a first attachment portion provided in the engagement portion, and a first storage member. The first storage member includes a first holding portion configured to hold a first electrode and be attached to the first attachment portion. The remanufacturing method includes detaching the first holding portion, attaching a second electrode to the frame member, and attaching a second storage element to the frame member at a different position from a position of the first attachment portion.

Cartridge and remanufacturing method of cartridge

Provided is an image forming unit including a photosensitive unit including an image bearing member, a developing unit including a developer bearing member and a container capable of containing a developer, a rotation shaft, the developing unit being rotated around the rotation shaft and positioned at one of a development position where the developer bearing member supplies the developer to the image bearing member and a separation position where the developer bearing member separates from the image bearing member, and a sensing portion sensing a variation or an amount corresponding to an amount of the developer contained in the developing unit. The rotation shaft is located below a developing portion, which is formed of the image bearing member and the developer bearing member, in a gravity direction.

Image forming unit and image forming apparatus

Provided is an image forming unit including a photosensitive unit including an image bearing member, a developing unit including a developer bearing member and a container capable of containing a developer, a rotation shaft, the developing unit being rotated around the rotation shaft and positioned at one of a development position where the developer bearing member supplies the developer to the image bearing member and a separation position where the developer bearing member separates from the image bearing member, and a sensing portion sensing a variation or an amount corresponding to an amount of the developer contained in the developing unit. When the developing unit is at the separation position, the sensing portion restricts the rotation of the developing unit thereby receiving a force from the developing unit.
