ABSTRACT:
An aperture electrode body of an image forming apparatus according to the invention comprises an insulating sheet made of polyimide as a base material and having a number of apertures and control electrodes for controlling a flow of toner. Reinforcing resin sheets made of polyimide are integrally affixed on both upper and lower surfaces of the insulating sheet. Since the aperture electrode body is prevented from warping due to the difference in characteristics of their materials, a uniform contact state with a toner carrying roller is obtained to thereby control a flow of toner in a stable manner.
