Filed: 1989-09-08
Abstract: PURPOSE:To prevent the occurrence of defects such as void by making accute an angle formed with the end surface of one material in contact with the superimposed surface of the other material and a superimposed surface. CONSTITUTION:The image forming device superimposes an exposed photosensitive material 16 on an image receiving material 48, and transfers and forms an image on the image receiving material 48.
