Abstract

PURPOSE: To make possible good transfer by the use of a one-component type developer by exposing the entire surface of the photoreceptor formed with toner images then contacting a grounded conductive roller to the back of the transfer paper contacted to the toner images.
CONSTITUTION: A photoreceptor 1 is charged to positive polarity by a charging charger 4 and forms electrostatic latent images by the image light 5 being radiated. The latent images are developed by conductive magnetic toner 7 in a magnetic brush developer 6 to form the toner images of negative polarity. Next, the electrostatic latent images are annihilated by the full surface exposure by an exposure lamp 8 and at the same time the negative charges of the toner images are further increased by the full surface charging with a charging charger 9. Next, transfer paper 11 is contacted onto the toner images and is moved by a grounded conductive rubber roller 10. When the charges of positive polarity are induced on the paper 11 in correspondence to the toner images and the paper 11 is peeled from the photoreceptor 1 by a peeling charger 12, the toner images are efficiently transferred to the paper 11 side and are heat-fixed by a fixing device 13.
