ABSTRACT:
An image forming apparatus has an image former for forming an image on a sheet at a predetermined image-forming speed; a plurality of feeders; a carrier for carrying the sheet fed from either of the feeders to the image former; and a controller for controlling the carrier to suspend the sheet fed from either of the feeders at a first position upstream of the image former. The controller determines whether a subsequent sheet is suspended at a second position upstream of the first position and/or controls a speed at which the carrier carries the sheet, based on a feeder that feeds the sheet among the plurality of feeders and/or on the image-forming speed of the image former.
