An image forming apparatus capable of matching, with high precision, the timing of the paper arriving at the transfer position and the timing of the toner image arriving there and not requiring the detection of the front end position of the toner image as by a sensor for the matching of the timings. The image forming apparatus has an image forming unit to make an image on image carriers, a transfer unit to transfer the image on the image carriers onto the paper, a transporting unit to transport the paper toward the transfer unit, a calculation unit to calculate a time when the image on the image carriers will arrive at the image transfer position or nearby position and correct the calculated result according to a predetermined parameter, and a control unit to control the paper transporting operation of the transporting unit according to the time determined by the calculation unit.
