Abstract
An example image forming apparatus includes, a main body, a first fixing device disposed in the main body to primarily fix a toner image transferred on a printing medium while passing through a transfer device, a first discharge device to discharge the printing medium having passed through the first fixing device from the main body, and a second fixing device disposed in the main body to additionally fix the toner image on the printing medium having passed through the first fixing device, wherein the second fixing device may be supplied with the printing medium through a connection path returning from the first discharge device into the main body and connected to the second fixing device.
Claims15
An image forming apparatus comprising:
- a main body;
- a first fixing device disposed in the main body to primarily fix a toner image transferred on a printing medium while passing through a transfer device;
- a first discharge device to discharge the printing medium having passed through the first fixing device from the main body;
- and
- a second fixing device disposed in the main body to additionally fix the toner image on the printing medium having passed through the first fixing device,
- wherein the second fixing device is supplied with the printing medium through a connection path forming a connection from the first fixing device to the second fixing device.
An image forming method, comprising:
- transferring an image to a printing medium;
- primarily fixing a transfer surface of the printing medium to which the image is transferred;
- disposing the printing medium in a different space from a space in which the primary fixing occurs by moving the printing medium backward from the space in which the primary fixing occurs and then moving the printing medium forward to the different space;
- and
- secondarily fixing the transfer surface of the printing medium in the different space.
