Abstract
PURPOSE:To raise the durability of a temperature sensor and to execute the precise control of an electrification temperature by setting the temperature sensor on a proper position where the temperature of the surface of an image carrier can be detected without contacting the temperature sensor with the surface of the image carrier. CONSTITUTION:As the setting position of the temperature sensor 58, for example a position where the detected temperature following the change of the temperature of the surface of a photosensitive body drum 20, which rises according to the number of copied sheets at the time of continuously copying, can be obtained is selected and the said sensor is mounted without contacting with the surface of the photosensitive body drum 20. Then, the change of a temperature control level caused by the decay of the surface of the temperature sensor 58, a fault in transfer caused by the exfoliation of an electrostatic latent image developing layer on the surface of the photosensitive body drum 20, the stain caused by the adhesion of toner on the surface of the temperature sensor 58 and the stagger of temperature between a detection part and an image part caused by the generated heat by the friction of the photosensitive body drum 20 with the surface of the temperature sensor 58 can be surely prevented. Thus, the life of the temperature sensor can be semipermanently prolonged and the precise control of the temperature can be executed.
