摘要： A light amount detector includes the following elements. An irradiation unit irradiates an image carrier with detection light. A light receiver receives reflected light obtained as a result of being reflected by the image carrier. A housing stores therein the irradiation unit and the light receiver and includes an opposing surface which opposes the image carrier. A window section includes a detection surface through which the detection light is emitted and the reflected light is received. The window section is supported by the housing and is disposed such that the detection surface is positioned farther inward than the opposing surface of the housing. The window section transmits the detection light and the reflected light.
