PROBLEM TO BE SOLVED: To make it possible to suppress the rubbing flaws of a transporting belt and intermediate transfer belt by the magnetic carrier in a two-component developer by using the resin magnetic carrier having a binder resin and cores consisting of a magnetic metal oxide and nonmagnetic metal oxide as the magnetic carrier. SOLUTION: The resin magnetic carrier which has the binder resin and the cores consisting of the magnetic metal oxide and nonmagnetic metal oxide and is formed by a method including or not including a polymerization method is used as the magnetic carrier. This resin magnetic carrier is formed to a spherical shape in its shape has the less friction to the transporting belt 130. Since the surface is soft, the magnetic carrier is transported by the transporting belt 130 and the flawing of the surface of the transporting belt 130 by the contact with photosensitive drums 3a to 3d or the rubbing with the cleaner 22 of the transporting belt 130 is substantially obviated. Then, the rear staining of the image or transfer defect by the cleaning defect of the transporting belt 130 is prevented and the image having good quality may be obtained. |
