Abstract
A laser printer is equipped with first to fourth motors, and controls independently first to fourth driving portions, respectively. The laser printer does a continuous double-side printing for a preceding paper and a following paper. When the preceding paper on a first surface of which the printing is applied is conveyed to a predetermined position, the laser printer feeds the following paper. When the preceding paper exceeds a sensing range of a paper sensor, the laser printer conveys the preceding paper at a high-speed re-conveyance velocity in a switchback mode. When the feeding of the following paper is done normally, the laser printer conveys the preceding paper to a re-conveyance path while lowering the conveyance velocity to a normal re-conveyance velocity. When an error occurs in the feeding of the following paper, the laser printer stops the conveyance of the preceding paper in the switchback mode.
