Abstract
A first conveying mechanism includes an intermediate conveying roller for conveying a recording sheet, an intermediate conveying roller shaft for supporting the intermediate conveying roller, an intermediate conveying roller drive mechanism for rotationally driving the intermediate conveying roller shaft, and a roller control mechanism for controlling movements of the intermediate conveying roller relative to the intermediate conveying roller shaft. The roller control mechanism performs skew correction along with conveying the recording sheet by rotating the intermediate conveying roller integrally with the intermediate conveying roller shaft while the intermediate conveying roller drive mechanism rotationally drives the intermediate conveying roller shaft and stops the rotational drive of the intermediate conveying roller shaft performed by the intermediate conveying roller drive mechanism after the skew correction to cause the intermediate conveying roller to be movable within a predetermined range in the axial direction of the intermediate conveying roller shaft.
