摘要： An image forming apparatus includes a transfer unit, a fuser unit, a detector, and an adjustment mechanism. The transfer unit transfers an image from an imaging surface to a recording sheet passing through a transfer nip. The fuser unit fixes the transferred image in place on the recording sheet passing through a fixing nip. The transfer nip and the fixing nip form part of a sheet feed path along which a recording sheet is fed from the fuser unit to the transfer unit. The detector is located between the transfer nip and the fuser unit, and detects an amount of sheet skew by which the fed recording sheet is deviated from a proper position in the sheet feed path. The adjustment mechanism adjusts position of either or both of the transfer unit and the fuser unit according to the detected amount of sheet skew.
