Abstract
An image forming apparatus includes an image bearing member unit; a developing unit; an accommodating portion configured to accommodate the image bearing member unit and the developing unit and provided with an inserting opening; a door for the opening; a pressing mechanism for pressing and releasing the image bearing member unit and the developing unit relative to each other in interrelation with the openable member; and a contact surface provided on the openable member, the contact surface is contactable with an upstream end portion of one of the units, when the openable member is closed in a state that the upstream end portion is projected out of the opening, wherein an angle formed between a normal line of the contact surface and the inserting direction in a downstream side is not less than 90 degrees.

1-6. (canceled)
An image forming apparatus comprising:
- a drum unit which includes a photosensitive drum rotatable about a rotational axis thereof by receiving a driving force and on which an electrostatic latent image is formed, said drum unit is capable of being mounted to an installation position in said image forming apparatus;
- a developing unit including a developer carrying member configured to carry a developer to develop the electrostatic latent image, with toner contained in the developer;
- an elastic member configured to apply an urging force to said drum unit toward an upstream side of an insertion direction of said drum unit;
- and
- an engaging portion configured to engage with said drum unit receiving the urging force to restrict movement of said drum unit from the installation position toward the upstream side in the insertion direction;
- wherein said drum unit further includes a release member configured to release engagement between said drum unit and said engaging portion, and
- wherein said drum unit is moved toward the upstream side by the urging force upon the engagement between said drum unit and said engaging portion by said release member.
