Abstract

Provide is an image forming apparatus that is capable of prolonging the service life of an intermediate transfer medium by making the intermediate transfer medium unlikely to degrade and unlikely to become damaged. An image forming apparatus 1 comprises a transfer means for transferring a toner image carried by image carriers 7Y, 7M, 7C, and 7Bk to a transfer target 33. The transfer means is configured by being provided with: an intermediate transfer belt 12 which rotates in contact with the surfaces of the image carriers 7Y, 7M, 7C, and 7Bk and to which the toner image is primarily transferred from the image carriers 7Y, 7M, 7C, and 7Bk; and an intermediate transfer roller 20 which rotates in contact with the surface of the intermediate transfer belt 12, to which the toner image is secondarily transferred from the intermediate transfer belt 12, and which tertiarily transfers the toner image to the transfer target 33.

Description

technical field [0001] The present invention relates to an image forming apparatus that transfers toner to various transfer objects. Background technique [0002] Conventionally, as a technology of an image forming apparatus for transferring a toner image to ceramics such as ceramics and glass, for example, the technology disclosed in Patent Document 1 is known. [0003] As in Patent Document 1 figure 2 As shown, the image forming apparatus disclosed in Patent Document 1 is constituted to have: an OPC photoconductive drum 5 (image carrier) having a photoconductive layer; An electrostatic latent image is formed; a developing unit 8a (developing member) for attaching toner to the electrostatic latent image formed on the OPC photoconductive drum 5 to form a toner image; a transfer roller 7 (transfer member) ), which rotates in contact with the surface of the OPC photoconductive drum 5, is transferred (primary transfer) the toner image formed on the OPC photoconductive drum 5 ...
