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, by increasing a card conveying speed or reducing a feed speed of a transfer film 46 during a time from when transfer processing for a card K to immediately before or after the card front end rushes into a conveying roller pair 37, excessive loosening of the transfer film 46 occurring on the card rear end side is eliminated. After the card rear end passes through the transfer roller 33, the feed speed of the transfer film 46 is further reduced to eliminate the loosening of the transfer film 46 on the card rear end side.

Abstract: To provide a transfer apparatus that uniforms peeling characteristics and peeling characteristics in transfer processing and that enables a stabilized transfer result to be obtained, in a transfer apparatus for nipping a transfer film 46 and recording medium K with a transfer roller 33 and transfer platen 31 to form an image on the recording medium, preheating treatment of the recording medium K is performed before transfer processing. At this point, by determining a preheating amount corresponding to the temperature of the recording medium K, it is possible to obtain a stabilized transfer result in response to a change in transfer conditions due to a change in environmental temperature and a change in the transfer surface. Particularly, in the case of performing backside transfer subsequently to frontside transfer, since the temperature of the recording medium K is high, a preheating amount in backside transfer is made smaller than in frontside transfer.

Abstract: Bookbinding apparatus adhesive applicator accurately, briefly controls adhesive temperature to a set value by selecting, in accordance with adhesive initial temperature, one of a plurality of temperature-controller heating modes defining different supply powers and supply durations for supplying power to an adhesive-container heater to control its heating temperature. A sensor detects the temperature of the adhesive in the container at applicator start-up, or on restarting a post-standby applicator. In accordance with the detected temperature, one of the heating modes is selected to heat the adhesive. The applicator warm-up time is thus set in response to the state of the adhesive: If solidified, the adhesive is heated and melted in a maximum supply-power, supply-duration mode; if low-temperature liquefied at, it is heated and melted in a second-magnitude supply-power, supply-duration mode; and if the adhesive temperature is high, it is heated and melted in a minimal supply-power, supply-duration mode.
