Lens mirror array

Abstract

A lens mirror array includes a plurality of optical elements arrayed in a main scanning direction. Each of the optical elements includes an incident surface, at least one reflection surface, and an emission surface. The incident surface transmits and converges light made incident thereon. The reflection surface has positive optical power for reflecting and converging the light made incident via the incident surface. The emission surface emits the light reflected by the reflection surface. The lens mirror array includes a plurality of grooves and a light blocking member. The plurality of grooves are provided among a plurality of the reflection surfaces arranged in the main scanning direction of the plurality of optical elements. The light blocking member is provided in the plurality of grooves.
