Abstract
A cartridge includes a casing, a photosensitive drum rotatably supported by the casing, a charging roller rotatably supported by the casing, and a developing roller rotatably supported by the casing. A shield member is supported by the casing and including a shield portion capable of covering a photosensitive member, the shield member being movable between a first position in which the shield portion covers the photosensitive member and a second position in which the photosensitive member is more exposed to outside of the cartridge by the shield portion than when the shield member is in the first position. An engaging portion is engageable with the shield member to hold the shield member in the second position when the shield member is in the second position, and a force receiving portion is provided for receiving an external force to disengage the engagement between the engaging portion and the shield member.
