Abstract
An image forming apparatus includes a controller including a primary heating control portion to control a heater to perform a primary heating to heat a fixing rotator with a first amount of power determined based on a temperature of the fixing rotator, a secondary heating control portion to control the heater to perform a secondary heating to heat the fixing rotator with a preset second amount of power, and a switch portion to control the heater to switch between the primary heating and the secondary heating during an identical print job and to perform at least one of a primary switching from the primary heating to the secondary heating and a secondary switching from the secondary heating to the primary heating at a time different from a preset control cycle that defines a power supply time in the primary heating and the secondary heating.
