ABSTRACT:
An image forming apparatus forms an image on a photosensitive recording medium by sequentially exposing light using each of plural mask members to form a component part of the image. A positioning mark is formed on each mask member. The apparatus comprises a mask member moving unit for moving the mask member and a sensing unit including a sensor for sensing the positioning mark and a supporting member formed so that a lower portion of the supporting member comes into contact with the mask member. The apparatus further comprises a controlling unit for controlling said mask member moving unit so that the mask member may be moved to a predetermined position on the photosensitive recording medium on the basis of a signal from the sensor. The sensing unit includes a recess corresponding to each sensor location. The distance between the sensor and the mask member can always be kept constant through the supporting member, because the supporting member comes into contact with the mask member. The accuracy of the positioning is, therefore, improved.
