Patent ID: 8886085

Claim:
An image forming apparatus that forms an image on a recording medium in a state in which a cartridge, including a photosensitive member, is removably mounted to a main body of the apparatus, the image forming apparatus comprising: a light emitting device that includes multiple light emitting portions, provided in a rotation axis direction of the photosensitive member, that illuminate in association with image information, the light emitting device being movable between (i) an exposure position for exposing the photosensitive member to illumination by the multiple light emitting portions and (ii) a retracted position retracted away from the photosensitive member relative to the exposure position; a support member that supports the light emitting device, wherein the light emitting device is movable by movement of the support member, the support member being movable between (i) a first position that allows for positioning the light emitting device at the exposure position and (ii) a second position that positions the light emitting device at the retracted position; and a separating member separating the light emitting device from the photosensitive member, wherein, in a state where the cartridge is mounted to the main body of the apparatus and the support member is positioned at the first position, the separating member regulates the light emitting device from moving to the exposure position by separating the light emitting device from the photosensitive member.
