Abstract
An exposure device includes a polygon motor, an f¸ lens, and a heat-insulating room. The polygon motor is driven into rotation while producing heat, which makes it likely that the temperature of a portion of the f¸ lens near a housing right wall becomes lower than that of a portion of the f¸ lens near a housing left wall. The exposure device further includes a recess located above the f¸ lens and extended in a right-and-left direction. The heat-insulating room is formed by disposing a plate above the portion of the f¸ lens near the housing right wall to cover the recess. Thus, the plate restricts upward heat release from the portion of the f¸ lens near the housing right wall.
