ABSTRACT:
An image forming apparatus includes an intermediate transfer belt having a coated layer as a surface layer that carries an developer image on the surface layer, a light-emitting member that emits light rays having a predetermined wavelength toward the surface layer of the intermediate transfer belt, and a sensing member that senses the light rays reflected from the intermediate transfer belt. The intermediate transfer belt includes a metal layer whose light reflection coefficient is larger than that of the coated layer and an intermediate layer positioned between the coated layer and the metal layer, and the intermediate layer that restrains the different light rays having a wavelength other than the predetermined wavelength from reflecting from the intermediate transfer belt.
