Abstract

The present invention provides an image forming apparatus in which an intermediate transfer medium is less likely to be damaged and deteriorated, and can achieve a longer life of the intermediate transfer medium. An image forming apparatus (1) structurally includes a transfer member for transferring a toner image carried on an image carrier (7Y, 7M, 7C, 7Bk) to a transfer object (33). The transfer member is configured to have an intermediate transfer belt (12) capable of rotating while being in contact with the surface of the image carrier (7Y, 7M, 7C, 7Bk) and transferred from the image carrier (7Y, 7M, 7C, 7Bk) primary transfer of the toner image; and an intermediate transfer roller (20) capable of rotating while being in contact with the surface of the intermediate transfer belt (12), which is secondarily transferred from the intermediate transfer belt (12) The toner image is transferred, and the toner image is transferred three times to the object to be transferred (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 ...
