Reflection-type light modulation array device and image forming apparatus

Abstract

A reflection-type light modulation array device, including: a plurality of light modulation devices arranged in a array form, each of which includes a displaceable light reflecting member capable of having an ON state in which incident light is allowed to emerge to an image formation surface and an OFF state in which incident light is not allowed to emerge to the image formation surface, and light modulation is performed by individually controlling displacements of the light reflecting members; a substrate on which the plurality of light modulation devices are arranged in an array form; and a transparent member arranged to be opposite to the substrate through a gap, wherein the transparent member includes, at a position opposite to at least a part of an area of a gap between effective areas where the light modulation is performed on the substrate when viewed on a plane, a light shielding unit to prevent the incident light from entering the substrate.
