Abstract
An image forming apparatus includes an exposure head including a light emitting portion that includes a first electrode layer including a plurality of electrodes that are two-dimensionally arranged in a rotation direction and a rotational axis direction of a photosensitive member, a light emitting layer stacked on the first electrode layer, and a second electrode layer through which light is transmissible; and a controller configured to control a voltage applied to each of the plurality of electrodes in such a way that one pixel is formed by controlling the voltage applied to the plurality of electrodes arranged at different positions in the rotation direction, in which the plurality of electrodes are arranged in such a way that a pitch of the plurality of electrodes included in the first electrode layer in the rotation direction is an integer multiple of a resolution of an image formed by the image forming apparatus in the rotation direction, and the integer is greater than one.
