Abstract: The present invention is to eliminate loosening of a transfer film on a rear end side of a card caused due to collision of a front end of the card against a conveying roller pair provided downstream of a transfer roller to prevent wrinkles from occurring in a transferred image. A rotation amount of a card conveying motor SMr and a wind amount of a transfer film 46 (conveying amount of the transfer film) are compared after a front end of a card K rushes into a conveying roller pair 37 during transfer processing for the card K to thereby detect a slip amount of the card K. A card conveying speed and a transfer film feed speed are controlled in accordance with the detected slip amount so as to eliminate loosening of the transfer film 46.

Abstract: An image forming apparatus is provided that can adjust an inclination deviation even after a laser scanner unit and a photosensitive drum are embedded. A CPU 601 selects at least two screen angles from among screen angles, and generates image signals corresponding to the respective selected at least two screen angles, based on these angles. The CPU 601 causes light emitting elements to emit light beams at different emission timings with reference to a timing on which a BD 803 detects the light beam, based on a generated image signal, thereby forming latent images of test images on a photosensitive drum. The latent images formed on the photosensitive drum are developed, and test images are formed on a recording medium.
