ABSTRACT:
An electrode unit of an image forming apparatus has plural apertures that are formed in a row on an insulating sheet and control electrodes each of which is formed on the upper surface thereof in correspondence with each aperture. A rectifying unit is provided on an opposite surface of the insulating sheet to a surface of the insulating sheet on which the control electrodes are provided so that the guide unit is not overlapped with the apertures in a toner feeding direction. With this construction, toner carried on a portion of a toner carry roller that does not confront each aperture, is guided to a portion confronting each aperture by the rectifying unit through rotation of the toner carry roller, whereby a sufficient amount of toner is supplied to the apertures at all times. Therefore, a sufficient amount of toner can be supplied even in a high-speed recording operation, and an excellent recording operation can be performed.
