LIGHT EMITTING ELEMENT HEAD, LIGHT EMITTING ELEMENT ARRAY CHIP, AND IMAGE FORMING APPARATUS

摘要

A light emitting element head includes a first light emitting element array, a second light emitting element array, and an optical device. The first light emitting element array includes a plurality of light emitting elements arranged in a main scan direction. The second light emitting element array includes a plurality of light emitting elements arranged in the main scan direction. The optical device focuses a light output from the first light emitting element array and the second light emitting element array on a photoreceptor to form an electrostatic latent image on the photoreceptor. The first light emitting element array and the second light emitting element array are overlapped each other in a sub scan direction in an overlapping section. Interval between the light emitting elements of the first light emitting element array are different from interval between the light emitting elements of the second light emitting element array.
