摘要： Damages on fixing members caused by paper passing through can be reduced. The registration rollers 53 and the registration oscillation roller 54 are provided on an upstream side of a fixing nip portion in a conveyance path for paper P and have a function of moving the paper P being conveyed toward the fixing nip portion, in a paper width direction, and the control section 10 performs paper oscillation control and fixing unit oscillation control in correlation with each other, the paper oscillation control in which the registration rollers 53 and the registration oscillation roller 54 are controlled to oscillate a position on which the paper P passes through, and the fixing unit oscillation control in which the fixing unit oscillation motor 36 is controlled to oscillate the fixing unit.

摘要： An image forming apparatus which allows a user to freely select a desired image quality is provided. The control unit 60 sets a of registration set value A1 for determining a color registration error suppression level and a dropout set value. A2 for determining a dropout occurrence suppression level. Also, the control unit 60 sets a differential circumferential speed which is the difference between the circumferential speed of photoreceptor drums 1Y to 1K and the circumferential speed of an intermediate transfer belt 6 on the basis of the color registration set value A1 and the dropout set value A1. Then, the control unit 60 controls the belt drive motor 1 and the drum drive motor 62 on the basis of the differential circumferential speed which is set.

摘要： An image forming apparatus includes an adjustment unit that adjusts an image transfer position of the sheet of paper along a main scanning direction that is orthogonal to a transporting direction of the sheet of paper, a fixing unit that fixes on the sheet of paper an toner image using fixing rollers and performs a fluctuation of the fixing roller to the main scanning direction, a detection unit that detects whether or not the fixing rollers of the fixing unit nip the sheet of paper, and a controller. The controller controls the fixing unit to perform the fluctuation of the fixing rollers when determining that the fixing rollers of the fixing unit do not nip the sheet of paper based on a detection result of the detection unit.
