ABSTRACT:
An image forming apparatus includes an optical exposure unit for forming an image on photosensitive material by exposing the material with light beam generated from a first light beam source and transmitted through a photographic film; and a digital exposure unit for forming an image on the photosensitive material by exposing the material with light beam generated from a second light beam source according to digital image data. The optical exposure unit and the digital exposure unit share a single common exposure point. The optical exposure unit includes a masking mechanism for delimiting an exposure area on the photosensitive material, and this masking mechanism and a head module of the digital exposure unit are integrated together as a unit.
