  • Image forming apparatus
    Patent number: 11971673
    Abstract: An image forming apparatus includes a process unit, a heating unit, and a controller unit. The process unit is configured to transfer an image onto a sheet. The heating unit is configured to fix the image transferred at the process unit onto the sheet, and to transfer a transfer layer onto an image formed on a sheet overlaid on a multilayer film. The controller unit is capable of operating in a first printing mode in which processes of transferring an image at the process unit, fixing the image at the heating unit, and transferring the transfer layer at the heating unit are executed, and a second printing mode in which processes of transferring an image at the process unit and fixing the image at the heating unit are not executed, and a process of transferring the transfer layer at the heating unit is executed.

  • Image Forming Apparatus Capable of Inserting Sheet Tray in One Direction and Discharging Printed Sheet in Opposite Direction
    Publication number: 20230109925
    Abstract: An image forming apparatus includes a housing, a toner image forming portion, a foil transfer unit, a sheet tray, and a discharge portion. The toner image forming portion is provided in the housing and configured to form a toner image on a sheet. The foil transfer unit is configured to superpose a foil with a surface of the sheet. The sheet tray is installable in the housing in an inserting direction and configured to accommodate a sheet to be supplied to the toner image forming portion. The first discharge portion is configured to discharge the sheet from the foil transfer unit to the outside of the housing in a discharging direction opposite to the inserting direction. The second discharge portion is configured to discharge the sheet from the toner image forming portion to the outside of the housing without passing through the foil transfer unit in the discharge direction.
