Abstract
An image forming apparatus has a photo-conductor drum that bears a toner image, and a transfer roller that is rotated in contact with the photo-conductor drum. The transfer roller transfers the toner image borne on the photo-conductor drum onto a recording medium conveyed between the photo-conductor drum and the transfer roller. The image forming apparatus includes a controller for applying to the transfer roller a transfer bias voltage for transferring the toner image from the photo-conductor drum onto the recording medium. The transfer bias voltage is a convolution of DC component and AC component.
Claims8
