Abstract
An image recording apparatus having aperture electrode body formed with a plurality of apertures through which toners pass to deposit onto an image receiving member. The aperture electrode body includes an insulative substrate having the apertures and control electrodes formed over the insulative substrate and each surrounding each aperture. The aperture electrode body has a nature of bending due to difference in thermal expansion coefficient of the insulative substrate and the control electrodes. To provide uniform bending, dummy electrodes are formed over the insulative substrate. The dummy electrodes includes a first set of dummy electrodes positioned at upstream side of the control electrodes with respect to a running direction of the image receiving member. The dummy electrode also includes a second set of dummy electrodes positioned beside the extreme end of the control electrode in the array direction of the apertures.
