Abstract:
1. An image forming apparatus, comprising: a printing portion configured to print an image and including: an ordinary printing controller configured to cause the printing portion to perform ordinary printing at a first temperature as the fixing temperature; and an energy-saving printing controller configured to cause the printing portion to perform energy-saving printing at a second temperature as the fixing temperature, the second temperature lower than the first temperature, wherein the energy-saving printing controller selectively performs a first energy-saving printing of performing the energy-saving printing by setting the conveying speed to a first speed and setting the sheet interval to a first interval, and a second energy-saving printing of performing the energy-saving printing by setting the conveying speed to a second speed faster than the first speed and setting the sheet interval to a second interval larger than the first interval, in one-time printing job in the energy-saving printing, assuming that a printing job in which the number of copies to be printed is larger than a predetermined value is a non small-amount printing job, and a printing job in which the number of copies to be printed is not larger than the predetermined value is a small-amount printing job, the energy-saving printing controller selects the first energy-saving printing in initialization of the energy-saving printing, and switches the selection to the second energy-saving printing when the image forming apparatus is in the energy-saving printing, in the case where the small-amount printing job has been sequentially generated a predetermined number of times.
