Organic electroluminescent array exposure head, method of fabricating the same, and image forming apparatus using the same

摘要

An organic EL array exposure head integrated with microlenses for converging or diverging light from light-emitting parts is disclosed, together with a method of fabricating the exposure head and an image forming apparatus using the same. The organic EL array exposure head has an array of organic EL light-emitting parts arranged in the form of at least one row of pixels on a substrate of continuous length. A microlens formed by ink-jet printing is provided over a surface of each organic EL light-emitting part at a side thereof remote from the substrate.
