An image forming apparatus including first and second pairs of rollers for feeding a print medium; the second pair of rollers being disposed downstream from the first pair of rollers; a first detector for detecting the print medium slack in a specified degree by contact with the print medium, the first detector being disposed between the first pair of rollers and the second pair of rollers; a second detector for detecting either the first pair of rollers or the second pair of rollers need a specified value of driving torque; and a controller for controlling either a feeding speed at which the print medium is fed by the first pair of rollers or a feeding speed at which the print medium is fed by the second pair of rollers based on either outputs from the first detector or outputs from the second detector.
