ABSTRACT:
A surface of a photosensitive body is charged and exposed to light to form an electrostatic latent image that is developed with toner having the same polarity as the surface. The toner image is transferred to a transfer material. During non-image forming periods a first step of applying a first voltage having the same polarity as that of the surface of the photosensitive body and an absolute value larger than the electric image forming potential of the transfer member is performed for a first period of time. In addition, a second step of applying a second voltage having an absolute value smaller than the absolute value of the electric potential of the surface of the photosensitive body to the transfer member for a second period of time not shorter than the first period of time is performed alternately with the first step.
