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 main scanning direction and a sub-scanning direction, 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 the light emitting layer emits light, in which the plurality of electrodes for forming an identical pixel are arranged in such a way that the electrodes partially overlap each other when viewed from the rotation direction, and an inter-centroid distance of the plurality of electrodes in the rotational axis direction is equal in the rotational axis direction, and d3=W1/n (n is a natural number of 2 or more), in which W1 [mm] is a width of the electrode in the rotational axis direction, n is the number of electrodes for forming the identical pixel, and d3 [mm] is the equal inter-centroid distance in the rotational axis direction.
