Abstract

A belt fixing system for fixing a toner image to a sheet includes an endless belt. This belt is rotatably supported by a plurality of supporting members, or rollers. Also, the belt is heated by a heater such as lamp and rotated around the supporting members by a drive member such as motor. When a toner fixing has finished, the heater is switched off and then after a predetermined time period the drive member is halted. Preferably, the time period is a time required for the belt to make two revolutions. This approach prevents the belt from being heated too much, which extends the durability of the belt.
