ABSTRACT:
A method of supplying recording sheets from a plurality of paper supplying units to a reference position within a main body of an image forming apparatus which forms an image on each of the sheets supplied successively from the paper supplying units via corresponding transport paths having different lengths comprises the steps of receiving from the units data related to the lengths of the transport paths between the units and the reference position, calculating from the received data a time when a supply of a second sheet is to start from a second unit which is designated relative to a time when a first sheet supplied from a first unit which is designated reaches the reference position when it is assumed that the length of the corresponding transport path from the first paper supplying unit is zero, and driving the first and second units with timings based on the calculated times, so that a recording speed of the image forming apparatus is maintained constant regardless of the length of the transport path used.
