摘要： Disclosed is a layer transfer device which transfers a layer of a multilayer film onto a surface of a sheet. The layer transfer device includes a heating member including a first portion and a second portion, a first heater, a second heater, and a controller. The controller is configured to control the first heater with an input power set at a predetermined input power, control the second heater with an input power set at a first input power if both of the multilayer film and the sheet pass over a surface of the second portion, and control the second heater with an input power set at a second input power that is smaller than the first input power if at least one of the multilayer film and the sheet does not pass over the surface of the second portion.

摘要： In a foil transfer device for transferring a transfer layer from a foil film onto a sheet laid on the foil film, the foil film is wound on a supply reel, and taken up on a take-up reel. A heating member heats the foil film, and a pressure member is provided to press the foil film and the sheet between the pressure member and the heating member. A separator changes a traveling direction of the foil film having passed through between the heating member and the pressure member into a direction different from a direction of conveyance of the sheet, to thereby separate the foil film from the sheet. A first fan blows air toward the foil film positioned between the heating member and the separator.

摘要： A fixing device includes a guide member including a guide portion, which is disposed downstream from a nip in a rotational direction of an endless belt and is in contact with the endless belt, and a gap forming portion, which is disposed between the nip and the guide portion in the rotational direction of the endless belt and which forms a gap from the endless belt. The gap forming portion includes an inclined surface that extends from the guide portion upstream in the rotational direction and has a predetermined area, on which a lubricant is provided. A maximum inclination angle between the predetermined area and a plane that is defined to contact a downstream end, in the rotational direction, of the contact portion of the nip member and the guide portion is less than 90 degrees.
