Abstract
A line sensor that detects the edge position of a recording paper is provided on the upstream side of a transfer point where an image formed on a first photosensitive drum is transferred to the recording paper. When performing borderless image formation, the size of the image on the first photosensitive drum to be transferred to the midstream of the recording paper after detection of its edge position is changed to a smaller size based on the detection results by the line sensor, and subsequent image formation to the recording paper continues to be performed according to this image on the photosensitive drum whose size has been changed.
