    摘要: An image forming apparatus includes: a sheet tray; an image forming unit that forms an image on a recording sheet; a sheet transporting path that allows a transportation of the recording sheet fed from the sheet tray to the image forming unit; and a sheet detecting unit that detects a passage of a rear end, with respect to a direction in which the recording sheet is transported, of the recording sheet along the sheet transporting path. The transportation of the recording sheet is temporarily stopped at the time of, or after a predetermined time from when the rear end is detected by the sheet detecting unit. The transportation of the recording sheet is resumed on the basis of data on a size of the transported recording sheet and a timing of image formation by the image forming unit.

    摘要: An image forming apparatus includes a fixing device including a pair of first rotating members; a first transport path having a curved portion where a recording medium is curved, the first transport path being for transporting the recording medium to which the image is fixed by the pair of first rotating members; a first transporting section including a pair of second rotating members provided downstream from the curved portion of the first transport path; and a controller that controls so that, while the recording medium is interposed between the pair of first rotating members and the pair of second rotating members, a peripheral velocity of the second rotating members and a peripheral velocity of the first rotating members are reduced at the same time, or the peripheral velocity of the second rotating members is reduced before reducing the peripheral velocity of the first rotating members.
