Process cartridge and image forming apparatus

摘要

A process cartridge is configured to be mounted in an apparatus main body along a predetermined mounting direction. The process cartridge may include a photosensitive drum; a drum drive input member into which a driving force for rotating the photosensitive drum is configured to be inputted; and a frame which holds the photosensitive drum and the drum drive input member. The frame includes a substantially cylindrical first protecting member which is formed on the frame. The first protecting member is configured to accommodate the drum drive input member, and project in a rotational axis direction of the photosensitive drum, wherein a projecting amount of a portion of the first protecting member which lies at a downstream side in the mounting direction is smaller than a projecting amount of a portion of the first protecting member which lies at an upstream side in the mounting direction.

主权项

1. A process cartridge comprising:
a photosensitive drum that is configured to be rotatable around a first rotational axis extending in a first direction; a coupling that is disposed at an end portion of the photosensitive drum on the first rotational axis of the photosensitive drum; and a projecting portion disposed around the coupling, the projecting portion projecting outwardly in the first direction, wherein the projecting portion has a first portion that has a first projecting amount and a second portion that has a second projecting amount larger than the first projecting amount.
