Patent ID: 7360887

Claim:
An image forming apparatus, comprising: a first inkjet head which ejects ink for forming a first image to be recorded on a recording medium; a first intermediate transfer medium on which the first image is formed by the ink ejected from the first inkjet head, the first intermediate transfer medium having a structure that includes an elastic body in a first image formation area in which the first image is formed; a second inkjet head which ejects ink for forming a second image to be recorded on the recording medium; a second intermediate transfer medium on which the second image is formed by the ink ejected from the second inkjet head, the second intermediate transfer medium having a structure that includes an elastic body in a second image formation area in which the second image is formed; and a transfer recording device which transfers and records the first image and the second image to a first surface of the recording medium in contact with the first image formation area and a second surface of the recording medium in contact with the second image formation area, while holding the recording medium between the first intermediate transfer medium and the second intermediate transfer medium, and conveying the recording medium with respect to the first intermediate transfer medium and the second intermediate transfer medium, wherein the elastic body in the first image formation area is a first transfer belt, and the elastic body in the second image formation area is a second transfer belt, and wherein the transfer recording device comprises a pressure adjustment mechanism which varies a pressure for holding the recording medium between the first intermediate transfer medium and the second intermediate transfer medium; the image forming apparatus further comprising: a pressure control device which controls the pressure adjustment mechanism in accordance with at least one parameter of a type of recording medium, a thickness of the recording medium, and a discharge amount of the ink; and a recording mode selection device which selects whether to carry out single-sided recording that records on one surface of the recording medium, or to carry out double-sided recording that records on both surfaces of the recording medium, wherein the pressure control device controls the pressure adjustment mechanism in accordance with a selection result of the recording mode selection device.
