Abstract
An image recording medium includes two sheets made of resin and a toner image interposed between the two sheets. The toner image serves as an adhesive to bond the two sheets together and includes an information image. At least one of the two sheets includes a transparent portion to enable the information image to be visible through the at least one of the two sheets.
Claims20
An image recording medium comprising:
- a first sheet and a second sheet, each made of resin;
- and
- a first toner image including a first information image, and a second toner image including a second information image, the first and second toner images being interposed between the two sheets and serving as an adhesive to bond the two sheets together,
- wherein at least one of the two sheets has a transparent portion to enable the first and second information images to be visible through the at least one of the two sheets, and the first and second toner images are mirror images of one another.
1 more element
A method of producing an image recording medium, the method comprising:
- forming a toner image on a front surface of a first transparent resin sheet;
- forming a solid image on the toner image on the front surface of the first transparent sheet;
- applying pressure and heat to the toner image and the solid image on the front surface of the first transparent resin sheet to fix the toner image and the solid image on the front surface of the first transparent resin sheet;
- and
- applying pressure, or pressure and heat, to the first transparent resin sheet and a second transparent resin sheet to bond the first transparent resin sheet and the second transparent resin sheet together with the toner image and the solid image serving as an adhesive,
- the applying pressure, or pressure and heat, performed in a state in which the second transparent resin sheet is overlaid on the front surface of the first transparent resin sheet on which the toner image and the solid image are fixed.

An image forming apparatus configured to produce an image recording medium, the image forming apparatus comprising:
- an image forming device configured to form a toner image on a front surface of a first transparent resin sheet and form a solid image on the toner image on the front surface of the first transparent sheet;
- a fixing device configured to apply pressure and heat to the toner image and the solid image on the front surface of the first transparent resin sheet to fix the toner image and the solid image on the front surface of the first transparent resin sheet;
- and
- an adhesion device configured to apply pressure, or pressure and heat to the first transparent resin sheet and a second transparent resin sheet in a state in which the second transparent resin sheet is overlaid on the front surface of the first transparent resin sheet on which the toner image and the solid image are fixed, to bond the first transparent resin sheet and the second transparent resin sheet together with the toner image and the solid image serving as an adhesive,
- the adhesion device including at least one of the fixing device and a registration roller pair that feeds the first transparent resin sheet and the second transparent resin sheet to the image forming device.
