Abstract
An emitter emits light such that the light crosses a conveyance path. A reflector reflects the light. A receiver receives reflected light. A determiner determines that a sheet is present on the basis of an amount of reflected light. A controller may increase a light amount of the light-emitting unit from a first light amount to a second light amount on the basis of a temperature of the light-emitting unit and a reflectance of the reflecting member. The controller may increase a receiving gain of the receiver from a first gain to a second gain on the basis of a reflectance of the reflecting member.
