Abstract
An edge electrode member includes an insulating sheet preferably made of polyamide, a number of control electrodes and a control voltage applying circuit provided on the insulating sheet. The control electrodes are formed independently of each other at a recording edge portion of the edge electrode member. The recording edge portion member is disposed upstream of the recording position so that the direction of an electric field coincides with the transport direction of the support member when control of flows of toner powder is changed. The image forming apparatus can output an image of a high picture quality free from toner powder trailing.
