Abstract
An image forming device includes a toner carrier ( ) for holding and conveying charged toner ( ), and a toner passage controller ( ) including a plurality of holes ( ) through which toner ( ) is passed and control electrodes ( ) disposed surrounding the holes. The control of passing of the toner ( ) through the holes is effected by applying voltage to the control electrodes in accordance with image signals. The holes ( ) have an elongated shape, with the length along a direction in which the toner carrier ( ) moves being longer than the width orthogonal to the lengthwise direction, so that the consumption areas of toner ( ) on the toner carrier ( ) do not interfere with each other while the open area of the holes ( ) is sufficiently secured.
