Abstract:
An image forming device comprising:a developer carrier (1) for carrying a charged developer (2); a developer passing controller (3) for controlling the passing of said developer (2) by applying a voltage corresponding to an image signal to a plurality of control electrodes (10), the developer passing controller having a plurality of developer passing holes (4) through which the developer (2) passes and said control electrodes being arranged to surround the surroundings of the developer passing holes; an image receiving member (7) for receiving said developer (2) passed through; and a backside electrode (6) for drawing said developer (2), the backside electrode being installed at the back side of said image receiving member (7), wherein the width of a control electrode row (5) in a longitudinal direction, where the control electrodes (10) are arranged, is wider than a width of an image forming area in a direction perpendicular to a moving direction of the image receiving member (7), and both ends of the control electrode row (5) in the longitudinal direction are arranged outside the width of an image forming area.
