Title:
IMAGE FORMING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/130685
Kind Code:
A1
Abstract:
This image forming device comprises: an exposure head including a plurality of light emitting units each including a first electrode layer, which includes a plurality of electrodes arranged two-dimensionally 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 can pass; and a control unit that controls the application of voltage to each of the plurality of electrodes so that the light emitting layer emits light. The plurality of electrodes for forming the same pixel are arranged such that some of the electrodes overlap each other when viewed from the rotational direction and the centers of gravity of the plurality of electrodes in the rotational axis direction are equidistant from each other in the rotational axis direction. When the width of the electrode in the rotational axis direction is W1 [mm], the number of the plurality of electrodes for forming the same pixel is n, and the distance between the centers of gravity at the same interval is d3 [mm], d3=W1/n (n is a natural number of 2 or more).
