Abstract
An image forming system includes an image forming unit which forms an image as a toner image on a printing medium, a first fixing unit which fixes, on the printing medium, the toner image formed by the image forming unit, a second fixing unit arranged at a position different from the first fixing unit and used when a larger amount of heat is necessary for fixing the toner image on the printing medium, and a changing unit which changes the sequence of image formation by the image forming unit when the second fixing unit is used during image formation.
Claims18
An image forming system comprising:
- an image forming unit adapted to form an image as a toner image on a printing medium;
- a first fixing unit adapted to fix, on the printing medium, the toner image formed by said image forming unit;
- a second fixing unit arranged at a position different from said first fixing unit and used when a larger amount of heat is necessary for fixing the toner image on the printing medium;
- and
- a changing unit adapted to change a sequence of image formation by said image forming unit when said second fixing unit is used during image formation.
A control method of an image forming system, comprising the steps of:
- forming an image as a toner image on a printing medium;
- performing first fixing to fix, on the printing medium, the toner image formed in the image forming step;
- performing second fixing to fix the toner image on the printing medium when a larger amount of heat is necessary for fixing the toner image on the printing medium;
- and
- changing a sequence of image formation in the image forming step when the second fixing step is executed during image formation.
