ABSTRACT:
An image forming apparatus is provided, in which a plurality of toner passage holes are formed in a board, and an image information generator applies a voltage between a pair of electrodes to form an electric field within each toner passage hole, so as to pass toner through the toner passage hole. The diameter and the axial length of each toner passage hole are so determined as to avoid clogging with toner.
