Abstract: An elastic force of an elastic member 11 required for rotating a driven rotational body 8b is decreased.A first rotational body 8d and a second rotational body 9a arranged downstream of a driven rotational body 8b in a drive train that transmits a driving force from a driving rotational body 7 to a driven member 4 are included. The first rotational body 8d rotates in synchronization with the driven rotational body 8b. The second rotational body 9a is rotated by the first rotational body 8d and rotates the driven member 4. The first rotational body 8d rotates without rotating the second rotational body 9a when the driven rotational body 8b rotates by an elastic force of an elastic member 11.

Abstract: An endless belt is held by a first roller and a second roller each having an axis extending in an axial direction. A transfer member is disposed opposite to an image supporting member with the belt therebetween. The transfer member is configured to transfer a developer image supported by the image supporting member to a sheet conveyed by the belt. The image supporting member extends in the axial direction. The belt and the transfer member each have a width in a direction parallel to the axial direction. A first portion of the image supporting member and a first portion of the transfer member directly oppose each other without the belt therebetween. A second portion of the image supporting member opposes a first surface of the belt, and a second portion of the transfer member opposes a second surface of the belt, which is opposite to the first surface.

The curved surfaces have a center of curvature that coincides with a rotational center of the latent-image carrier, and are at a position where a distance from the latent-image carrier in a radial direction is equal to a distance between the latent-image carrier and the control electrode. When the charging member is attached to the latent-image forming member, the control electrode is abutted against the curved surfaces by the restraining portions and is deformed along the curved surfaces.

The developing cartridge includes a frame; a developer carrying member for carrying a developer for developing an electrostatic latent image; a portion to be guided for being guided by the mounting guide when the developing cartridge passes through the mounting guide; an accommodating portion for accommodating the developer; a seal member for unsealably sealing an opening for permitting supply of the developer from the accommodating portion to the developer carrying member; and a grip member, provided at a longitudinal end portion of the seal member, including a fixed portion dismountably fixed on the frame and a grip portion to be gripped when the seal member is removed. The grip portion is disposed in a state in which the grip portion is bent relative to the fixed portion in a direction crossing a mounting direction of the developing cartridge. The grip portion prevents mounting of the developing cartridge by contacting a part of the image forming apparatus when the developing cartridge is mounted in the main assembly of the image forming apparatus.
