Abstract: 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.

Abstract: Provided are a film cartridge, a film unit, and a layer transfer device capable of restraining a supported layer including a transfer layer from being touched by an operator and restraining the supported layer remaining on the supporting layer remaining on a supporting layer from coming off. A film cartridge includes a supply reel on which a multilayer film including a supported layer with a transfer layer included therein and a supporting layer is wound, and a take-up reel on which to take up the multilayer film. The multilayer film is wound on a supply shaft in such a manner that the supported layer is in contact with the supply shaft, and the multilayer film is wound on the take-up shaft in such a manner that the supported layer is in contact with the take-up shaft.

Abstract: Disclosed is a layer transfer device for transferring a transfer layer onto a toner image formed on a sheet, in which a replacement of a film cartridge is easy for a user. The layer transfer device includes a housing, a film cartridge, and a holder. The film cartridge includes a supply reel including a supply shaft on which a multilayer film including a supported layer including a transfer layer, and a supporting layer supporting the supported layer is wound, and a take-up reel including a take-up shaft on which to take up the multilayer film. The holder supports the film cartridge, and is installable into and removable from the housing while supporting the film cartridge.

Abstract: An image forming apparatus including: a main body housing; a drawer; a developing cartridge detachably supported by the drawer; a toner container configured to be mounted to and demounted from the main body housing; and a supply tube being movable between a connection position at which the supply tube is connected to the developing cartridge and is capable of supplying toner from the toner container to the developing cartridge supported by the drawer and a non-connection position at which the supply tube is not connected to the developing cartridge, wherein in a case where the drawer is moved from an inner position to an outer position in a state where the developing cartridge is supported by the drawer, the supply tube comes into contact with a part of the developing cartridge and is thus moved from the connection position to the non-connection position.
