摘要： An image forming apparatus includes: an image holder that holds a toner image; a transferer that is disposed opposite to the image holder so as to be in contact with the image holder and transfers the toner image from the image holder onto a recording sheet that is going through a contact part where the transferer contacts the image holder, by applying a transfer voltage between the transferer and the image holder; a first power source that applies a voltage of a first polarity to the image holder; and a second power source that applies a voltage of a second polarity, which is reverse to the first polarity, to the transferer.

摘要： An image forming device includes a resist roller feeding a sheet of paper toward an image forming unit; a first detector arranged upstream of the resist roller in a feeding direction to detect a front edge of the sheet of paper; a first calculator computing a first misalignment amount of the sheet of paper based on detection results by the first detector; a corrector correcting misalignment of the sheet of paper based on the computed first misalignment amount; a second detector arranged downstream of the resist roller in the feeding direction to detect a position of an end of the sheet of paper in a widthwise direction; a second calculator computing a second misalignment amount of the sheet of paper based on detection results by the second detector; and an adjuster adjusting a correction amount by the corrector based on the computed second misalignment amount.
