Abstract (en)

[origin: EP0351894A2] An image-forming machine comprising a main body (204) of the image-forming machine and a process unit (210) to be detachably mounted on the main body (204), said process unit (210) including a process unit frame (216) to be mounted on the main body (204) and an image bearing member (222) mounted on the process unit frame (216) and adapted to be moved in a predetermined direction, wherein an image-forming area (224) on which to form an image exists on a greater portion of the surface of the image bearing member (222) and a non-image-forming area (226) on which substantially no image is to be formed exists in the remainder of said surface, a transfer opening (292) for bringing a sheet material into intimate contact with the image-forming area (224) of the image bearing member (222) is formed in the process unit frame (216), and said machine is constructed such that when an image-forming step is over, the non-image-forming area (226) of the image bearing member (222) is positioned at the transfer opening (292) of the process unit (210).
