An apparatus for forming an image is provided that can sufficiently prevent
occurrence of nibbled images without any damage of the photoreceptor and
the intermediate transfer body, whereby good image quality can be stably
obtained for a long period of time. In an apparatus for forming an image
having an intermediate transfer body, the surface of the photoreceptor has
a dynamic hardness of 8.times.10.sup.9 N/m.sup.2 or more, and the surface
of the intermediate transfer body has a dynamic hardness larger than that
of the surface of the photoreceptor, and a difference between the dynamic
hardness of the surface of the photoreceptor and the dynamic hardness of
the surface of the intermediate transfer material is 2.times.10.sup.10
N/m.sup.2 or less.
