An electrophotographic image forming apparatus fuses an image to a recording medium by heat and pressure. To ensure that the recording medium does not stick to the fusing roller, a non-printable margin is normally reserved at the leading edge of the recording medium. When the recording medium has sufficient stiffness, however, as determined from its thickness and other factors such as its width or orientation, marginless printing is permitted. The setting of an unnecessary margin is thereby avoided.
