Abstract
An image-forming machine includes an image-bearing member having a photosensitive material on its surface, a latent electrostatic image-forming device for forming a latent electrostatic image corresponding to image information on the photosensitive material, a developing device for developing the latent electrostatic image, a transfer device for transferring the toner image from the photosensitive material to a sheet material, a conveying mechanism for conveying the sheet material through a transfer zone, and a receiving section for receiving the sheet material conveyed through the transfer zone. An assembly provides an improved cooperation of an optical device of the image-forming device, a sheet receiving section and the developing device. A further assembly maintains a process unit having the image-bearing member and an optical unit having the optical device in a predetermined positional relationship. Another assembly facilitates mounting and detachment of the image-bearing member on and from a process unit frame.
