    摘要： An image forming apparatus comprises: an image forming unit to form an image onto a recording medium; a measuring unit to measure a density of the image formed on the recording medium; a controller to execute an image stabilizing control to decide image forming conditions of the image forming unit on the basis of the image density measured by the measuring unit; a heater to heat a load by supplying a current to the image forming apparatus; and a detector to detect a temperature of the load which is heated by the heater, wherein the controller controls the execution of the image stabilizing control in accordance with an output of the detector at the start of the power supply to the apparatus. When the detected temperature of the load is less than a predetermined value, the image stabilizing control is executed. When it is equal to or higher than the predetermined value, the image stabilizing control is not performed. When the image stabilizing control is executed, the control means allows the image forming unit to form a sample image and the image forming conditions are controlled on the basis of the state of the sample image.
