Layer transfer device

A layer transfer device that overlaps a multilayer film having a plurality of layers with a surface of a sheet on which a toner image is formed, the layer transfer device being configured to transfer at least one layer of the multilayer film onto the toner image, the layer transfer device comprising:

• a sheet conveying unit configured to convey the sheet;
• a supply reel around which the multilayer film is wound;
• a wind-up reel configured to wind up the multilayer film from the supply reel;
• a film transfer unit configured to perform transfer in a state where the multilayer film supplied from the supply reel is overlapped with the sheet conveyed from the sheet conveying unit;
• and
• a peeling roller disposed between the film transfer unit and the wind-up reel in a conveyance path of the multilayer film, the peeling roller contacting the multilayer film having passed the film transfer unit, the peeling roller being configured to peel off the multilayer film from the sheet when a conveying direction of the multilayer film having passed the film transfer unit is changed to a direction different from a conveying direction of the sheet due to the wind-up reel winding up the multilayer film,
• wherein the film transfer unit includes:
• a first roller provided at a position to contact the sheet;
• and a second roller provided at a position to contact the multilayer film, and the film transfer unit overlaps the sheet with the multilayer film and is configured to heat and press the sheet and the multilayer film at a nip part of the first roller and the second roller, and
• wherein a tangent line of the second roller at a downstream end of the nip part in the conveying direction of the sheet passes between a center of the second roller and a center of the peeling roller, and an angle formed by the tangent line and a film tension portion of the multilayer film tensed between the nip part and the peeling roller is 15 degrees to 37 degrees.
