Image forming apparatus

摘要

An image forming apparatus includes an apparatus main body and a movable member configured to move with respect to the main body while supporting an image bearing member and a developer bearing member. The movable member is movable to a position located inside the main body, where the two bearing members is in an image formable state, and a position located outside the main body, where a cartridge including the developer bearing member is detachable from the movable member. The apparatus further includes an exposure device configured to expose the image bearing member via a light transmission member, and a cleaning member configured to clean a surface of the light transmission member opposed to the movable member. The cleaning member is provided on the movable member and is movable to a contact position for contacting the light transmission member and a noncontact position when the movable member moves.

1. An image forming apparatus comprising:
an apparatus main body; a movable member configured to move with respect to the apparatus main body in a state where the movable member supports an image bearing member on which a latent image is to be formed and a developer bearing member that bears a developer for developing the latent image, wherein the movable member is movable to an image forming position, located inside the apparatus main body, at which the image bearing member and the developer bearing member are brought into an image formable state and to an attachment/detachment position, located outside the apparatus main body, at which a cartridge including the developer bearing member is attachable/detachable to/from the movable member; an exposure device configured to expose the image bearing member to form the latent image by irradiating the image bearing member with light having passed through a light transmission member; and a cleaning member configured to clean the light transmission member according to a movement of the movable member between the image forming position and the attachment/detachment position, wherein the cleaning member is provided on the movable member and movable with respect to the movable member, so as to be movable to a contact position at which the cleaning member makes contact with the light transmission member when the movable member moves and a noncontact position at which the cleaning member does not make contact with the light transmission member when the movable member moves.
