Light emitting element array, exposing head using the same, and image forming apparatus using the same

Abstract

In a light emitting element array in which a plurality of components having multiple light emitting thyristors connected to a single shift thyristor are arranged in a plurality of lines, the density of the light emitting thyristor is increased without reduction in the amount of light emission of each of the light emitting thyristors. In the light emitting element array in which multiple light emitting thyristors are formed on a single island structure and the multiple light emitting thyristors are connected to a single shift thyristor, a first element-isolating groove that element-isolates the multiple light emitting thyristors from each other inside the single island structure is formed shallower than a second element-isolating groove that element-isolates the island structure.
