ABSTRACT:
The present invention provides an intermediate transfer belt, wherein: the intermediate transfer belt is made from a resin material comprising a carbon black in a dispersed state; an absolute value of a difference between a common logarithm value of surface resistivity 10 seconds after voltage application and a common logarithm value of the surface resistivity 30 milliseconds after voltage application is about 0.2 ((Log Ω/□) or less; and a Young's modulus thereof is about 3,500 MPa or more. The intermediate transfer belt is preferably formed by a process comprising: dispersing the carbon black in a polyamide acid solution to prepare a dispersant; developing the dispersant in a ring-like shape to form a developing layer; drying the developing layer to make a film to mold into a belt shape to form a molded article; and heat-treating the molded article to convert polyamide acid into imide.
