Process Cartridge and Image Forming Apparatus

An image forming apparatus comprising:

• a process cartridge;
• and
• an installation member into which the process cartridge is installed,
• wherein
• the process cartridge comprises:
• a frame that has an opening that is long in a predetermined direction;
• a photosensitive drum that is held in the frame, a portion of a surface of the photosensitive drum being opposite to the opening of the frame, the photosensitive drum extending along a longitudinal direction of the opening;
• a protection member that has:
• a linear body portion extending in the longitudinal direction;
• and
• a support portion extending from an end of the linear body portion in a direction perpendicular to the longitudinal direction,
• the support portion being supported on the frame so as to rotate about an axis that extends along the longitudinal direction, the linear body portion being movable between a protecting position and a retreat position, the protecting position where the liner body portion faces the opening in such a state that the liner body portion is not in contact with the frame, the retreat position where the liner body portion faces a peripheral portion of the opening of the frame;
• and
• a controllable portion that is fixed on the protection member and is operable to move the protection member,
• wherein
• the installation member comprises:
• a controlling portion that is configured to move the protection member from the protecting position to the retreat position by pressing the controllable portion to an upstream side in an installing direction of the process cartridge when the process cartridge is installed into the installation member.

An image forming apparatus comprising:

• an apparatus main body;
• a drawer frame that is removably installed in the apparatus main body;
• and
• a process cartridge that is detachably installed in the drawer frame in such a state that the drawer frame is drawn out of the apparatus main body;
• wherein
• the process cartridge comprises:
• a frame that has an opening that is long in a predetermined direction;
• a photosensitive drum that is held in the frame, a portion of a surface of the photosensitive drum being opposite to the opening of the frame, the photosensitive drum extending along a longitudinal direction of the opening;
• a protection member that has:
• a linear body portion extending in the longitudinal direction;
• and
• a support portion extending from an end of the linear body portion in a direction perpendicular to the longitudinal direction,
• the support portion being supported on the frame so as to rotate about an axis that extends along the longitudinal direction, the linear body portion being movable between a protecting position and a retreat position, the protecting position where the liner body portion faces the opening in such a state that the liner body portion is not in contact with the frame, the retreat position where the liner body portion faces a peripheral portion of the opening of the frame;
• and
• a controllable portion that is fixed on the protection member and is operable to move the protection member,
• wherein
• the apparatus main body comprises:
• a controlling portion that is configured to move the protection member from the protecting position to the retreat position by pressing the controllable portion to an upstream side in an installing direction of the drawer frame in response to an installing operation of the drawer frame into the apparatus main body.
