<P>PROBLEM TO BE SOLVED: To improve a sensing precision of a detection member. <P>SOLUTION: An image forming apparatus has an intermediate transfer belt provided with a painted layer as a surface layer and for carrying developer images on the surface layer, an emission member for emitting light having a prescribed wavelength toward the surface layer of the intermediate transfer belt, and a sensing member for sensing the light reflected by the intermediate transfer belt. The intermediate transfer belt comprises a metal layer larger than the painted layer by the reflectance of the light, and an intermediate layer for suppressing reflection due to the intermediate transfer belt of another beam of light having a wavelength other than the prescribed wavelength in the intermediate layer positioned between the painted layer and the metal layer. <P>COPYRIGHT: (C)2007,JPO&INPIT |
