ABSTRACT:
An electrostatic latent image formed on an image carrier is developed and then transferred to a paper sheet. In a normal copy mode, the image transferred to the paper sheet is fixed at a relatively high pressure, and in a multiple super position mode, it is fixed at a relatively low pressure. Thereafter, the paper sheet is conveyed again to a step for trasferring another image.
