Abstract
An auxiliary exposure device for an image forming apparatus which forms an image on a recording medium using slit-scanning exposure. The auxiliary exposure device comprises a reflection member which is insertable into and removable from a light path extending from a light source to a recording medium, a drive unit for moving the reflection member into and out of the light path, and a control unit for controlling a drive unit to adjust the amount of insertion of the reflection member into the light path. When the image to be copied is based on a photograph or like multi-toned original, requiring auxiliary exposure, the reflection member is inserted into the light path. In this state, when a part of an original image is irradiated by light emitted from a light source, the reflection surface of the reflection member is also irradiated. The light reflected from the original and the reflection surface of the reflection member pass to the photosensitive recording medium through the optical system and the primary exposure and the auxiliary exposure occur simultaneously.
