An image forming apparatus including a heating rotating body (first body) and a pressurizing rotating body (second body) disposed in a pressure contact state, and commencing image forming when a temperature of the first body reaches a predetermined temperature lower than a fixing temperature. The apparatus acquires a value indicating a temperature of the second body upon commencement of warm-up, and when the value is below a threshold value, heats the first body until the temperature thereof reaches the fixing temperature while rotating the two bodies at a first speed, and when the value equals or exceeds the threshold value, heats the first body until the temperature thereof reaches the predetermined temperature while rotating the two bodies at a second speed slower than the first speed and further heats the first body until the temperature thereof reaches the fixing temperature while rotating the two bodies at the first speed.
