Abstract

PURPOSE: To prevent occurrence of cold offset by enabling switching over or the like of developing bias voltage.
CONSTITUTION: Photosensitive drum 1 rotating in the arrow direction is charged with charger 2, imagewise exposed with a slit exposure system, the formed static latent image is developed with developing section 3 to a toner image, this is transferred to transfer paper with transfer section 13, this paper is separated with destaticizing separator 14, and the transferred image is fixed with fixing section 16. When successive copying is carried out by repeating these steps, bias voltage to be applied to cylindrical sleeve 5 is switched over, and image density on the transfer paper is changed in accordance with the lower temperature limit of fixing of section 16, or drive of toner feeder 9 is stopped.
