ABSTRACT:
In an operation for transporting a sheet by a first roller to a second roller pair downstream of the first roller, and further transporting the sheet by the second roller pair, the time during which the sheet is transported by the first roller is controlled, responsive to a comparison of a reference time and the actual time required for a sheet to be transported from the first roller to a predetermined position in the sheet transport path, to suppress disadvantages such as jamming and deformation into a Z-form, which may be caused by reduction of a transporting performance due to wear of the rollers and adhesion of paper powder to the rollers.
