There is provided an image forming apparatus. The image forming apparatus, after controlling so as to develop the developer image representing the predetermined image formed a plurality of times in the same location on an image carrier by an exposing component, controls such that without performing exposure with the exposing component, the developer image, developed on the image carrier by the developing component applying a biasing voltage to the developer so as to adhere the developer to the image carrier including to the same location on the image carrier, is transferred to the transfer component and detects whether or not a ghost image is generated by comparing the density detected by a detecting component at a position of a transfer body corresponding to the same location of the image carrier to a reference density.
摘要:
A transport belt has a belt base which is made of an elastic material, and a covering layer that covers a surface of the belt base. The covering layer contains an adherence repression filler to repress adherence to a contact member being in contact with a surface of the transport belt, which is dispersed at not less than 5 weight %.
摘要:
A transport belt of the invention is characterized by including a belt substrate including an elastic material, and a coating layer for coating the surface of the belt substrate, and is capable of directly or indirectly carrying an image formed by an image-forming particle. The coating layer has a thickness “h,” which is equal to or smaller than an average particle size “d” of the image-forming particle. A hardness-retaining filler which is capable of suppressing a drop in surface microhardness is dispersed in the coating layer.
