Abstract
An image forming apparatus includes a printer and a controller. The printer transfers an image formed by attaching toner to an electrostatic latent image onto a sheet, heats and presses the sheet onto which the visible image is transferred to fix the image onto the sheet, and thereby forms an image on the sheet. The controller controls the printer to form an image for a second surface, and then to form an image for a first surface which differs from a surface on which the image for the second surface is formed, when the controller determines that duplex printing, in which decolorable toner is used on the first surface on which an image is first formed, and toner having a fixing temperature higher than a decolorizing temperature is used on the second surface, is set in printing job data.
Claims16
An image forming apparatus comprising:
- a printer configured to transfer a visible image formed by attaching toner to an electrostatic latent image on a photoconductive drum onto a sheet, to heat and press the sheet onto which the visible image is transferred so as to fix the visible image onto the sheet, and to thereby form an image on the sheet;
- and
- a controller configured to
- control the printer to form an image for a second surface on a sheet, and then to form an image for a first surface on a surface which is different from a surface on which the image for the second surface is formed, when the controller determines that duplex printing is set according to job data to provide an instruction for image formation,
- wherein, in the duplex printing, decolorable toner is applied on the first surface which is a surface on which an image is first formed, of a front surface and a rear surface of a sheet, and toner having a fixing temperature higher than a decolorizing temperature of the decolorable toner is applied on the second surface, which is a surface on which an image is formed after the first surface.
An image forming method comprising:
- transferring, by a printer, a visible image formed by attaching toner to an electrostatic latent image on a photoconductive drum onto a sheet, and fixing the visible image onto the sheet to thereby form an image on the sheet;
- and
- upon determining that duplex printing is set according to job data to provide an instruction for image formation, controlling, by a controller, the printer to form an image for a second surface on a sheet, and then to form an image for a first surface on a surface which is different from a surface on which the image for the second surface is formed,
- wherein, in the duplex printing, decolorable toner is applied on the first surface which is a surface on which an image is first formed of a front surface and a rear surface of a sheet, and toner having a fixing temperature higher than a decolorizing temperature of the decolorable toner is applied on the second surface, which is a surface on which an image is formed after the first surface.
