    摘要： A toner density sensor has a light emitting unit that emits light to detect toner density, a light receiving unit that receives the light emitted from the light emitting unit and reflected from a detection target, and a board on which the light emitting unit and the light receiving unit are surface-mounted. A penetration space that penetrates the board in a thickness direction is formed in at least one of portions in which the light emitting unit and the light receiving unit are attached to the board.
