Abstract
A belt member for intermediate transfer, including a crosslinked product of a thermoplastic resin; and an electroconductive particulate material, wherein the belt member satisfies the following formulae (I) and (ii): 6≦log(ρv200)≦10 (i) 0≦log(ρv10)−log(ρv1,000)≦2 (ii) wherein ρv200, ρv10 and ρv1,000 represent volume resistivities when the belt member is applied with biases of 200 V, 10 V and 1,000 V, respectively.
