Abstract
A layer transfer device includes a supply reel, a take-up reel, a driving source, a releasable restraining device, a heating roller, a pressure roller, and a controller. The driving source drives the take-up reel. The releasable restraining device is capable of switching to a restraining state in which a multilayer film is put under restraint in being drawn out from the supply reel and to a release state in which the restraint is lifted. The controller is configured such that when the driving source is generating the mechanical power, the releasable restraining device is in the restraining state if an image area in which an image is formed on the sheet is not present in a layer transfer position between the heating roller and the pressure roller, and the releasable restraining device is in the release state if the image area is present in the layer transfer position.
