装置。 A paper feed section that supplies cut paper sheets one by one; a photosensitive drum and transfer belt that form toner images on the cut paper sheets sent from the paper feed section by electrophotography; a drive roller that drives the transfer belt; and a drive roller that drives the transfer belt. In an electrophotographic printing apparatus, the transfer belt is stretched between the drive roller, a driven roller that is driven by the drive roller, and a belt position detection means for detecting the position of the endless belt in the rotation axis direction. An electrophotographic printing apparatus comprising: a belt meander correction mechanism that changes the direction in which the endless belt moves in the axial direction on the drive roller by changing the parallelism between the belt and the driven roller.
