Abstract
An electrophotographic image forming apparatus and method of controlling the apparatus during a warm-up operation. During the warm-up operation, a heating unit for heating a fuser will be turned on and a motor for starting rotation of a photosensitive body will be activated when the temperature of the fuser reaches a motor rotation start temperature. When the temperature of the fuser reaches a warm-up completion temperature, the warm-up operation will be stopped and the rotation of the photosensitive body will be terminated. The warm-up completion temperature is higher than a stand-by temperature but lower than a fusing temperature.
