1. A layer transfer device for transferring a transfer layer onto an image formed on a sheet, the layer transfer device comprising:
a supply reel on which a multilayer film including a transfer layer and a supporting layer supporting the transfer layer is wound;
a take-up reel on which to take up the multilayer film;
a releasable restraining device capable of switching to a restraining state in which the 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;
a heating roller configured to heat the multilayer film and the sheet;
a pressure roller configured to be rotatable to convey the multilayer film and the sheet nipped between the pressure roller and the heating roller; and
a controller configured to switch the releasable restraining device to the restraining state and to the release state while the sheet is being conveyed in the layer transfer device.
