ABSTRACT:
Disclosed is an intermediate transferring belt utilized in order to transfer a toner image formed by developing a latent image on an image bearing member by means of a toner,wherein the intermediate transferring belt comprises a matrix and conductive fine particles, the conductive fine particles are dispersed into the matrix, and the surface resistivity ρs of the outer surface of the intermediate transferring belt is 1.0×109ohm/square to 1.0×1013ohm/square, andwherein the intermediate transferring belt is applied to an image forming apparatus of which transferring electric field is controlled to 15 MV/m or less when the toner image on the image bearing member is primarily transferred to the intermediate transferring belt.
