Abstract: In an image forming apparatus using an indirect transferring method, an ink ribbon is selectively heated by a thermal head, in a state where an intermediate transfer film and the ink ribbon are put one on the other on a platen roller, so that a record-image is formed as a mirror image on an image-forming layer of the intermediate transfer film. Then, the intermediate transfer film and a target object are supplied with heat and pressure between a heating roller and a pressure roller, so that the record-image is transferred along with the image-forming layer of the intermediate transfer film to the target object. The intermediate transfer film and the ink ribbon are respectively accommodated in cassettes detachably mounted in the apparatus, and are used for forming the record-image while being fed from the cassettes.

Abstract: An image forming apparatus uses an ink ribbon having ink layers of different colors, and a long, film-like intermediate transfer medium. A platen for holding the medium during transfer is driven by a motor via a synchronous reduction gear whose speed reducing ratio is an integer multiple. The ink ribbon is selectively heated by a thermal head having regular polygonal or circular heat-generating portions. Under the control of a controller, the thermal head is driven on the basis of image information, and a record image containing an area gradation image is formed on the medium. This area gradation image has a color set by stacking dots having different colors in the same spot. The medium on which the record image is formed is overlapped on a target body and heated and pressed by a heat roller, thereby transferring the record image from the medium onto the target body.

Abstract: The card producing apparatus which records magnetic data or printed data on many cards, which washes the cards and records predetermined data on predetermined areas of the cards so that there will not develop erroneous recording, and which rejects cards in case erroneous recording developed, all automatically. The card producing apparatus characterized by the structure comprising a feeder that takes out a predetermined number of accommdated cards every time, magnetic data recording means for recording magnetic data on cards, a cleaner for washing the surfaces of cards, a printer for printing data on the surfaces of cards, a stacker for accommodating cards on which data are recorded, card carrier devices in the apparatus, and a controller for controlling them.
