7. PRINT PROCESS
7-1. Image forming process
Normal paper is used as print paper. A laser beam is used to expose
on the OPC surface to form latent electrostatic images, which are
developed into visible images (toner images) and are transferred on
paper. The basic operation is composed of the five processes: charg-
ing, exposure, development, transfer, and cleaning.
