摘要： An image forming apparatus (100) includes an intermediate transfer device (7) that forms a primary transfer nip (PN) between a photoconductor (2) and the intermediate transfer device (7) and primarily transfers an image from the photoconductor (2) onto the intermediate transfer device (7) at the primary transfer nip (PN). A secondary transfer device (8) forms a secondary transfer nip (N) between the intermediate transfer device (7) and the secondary transfer device (8). The secondary transfer device (8) secondarily transfers the image from the intermediate transfer device (7) onto a recording medium at the secondary transfer nip (N). At least one support shaft (74) supports the intermediate transfer device (7). The at least one support shaft (74) supports, on an identical axis, one lateral end and another lateral end of the secondary transfer device (8) in a width direction of the recording medium.

摘要： An image forming apparatus includes: a transport unit that transports a recording medium whose image formation surface has electric conductivity; a transfer unit that makes contact with the image formation surface of the recording medium transported by the transport unit and transfers an image formed with particles onto the image formation surface by an electric field formed between the transfer unit and the image formation surface; and a support unit that has electric conductivity, supports the recording medium so as to be conductive with the image formation surface of the recording medium, and is transported to the transfer unit together with the recording medium by the transport unit.
