Abstract: The invention provides a developing apparatus in which toner is mixed with magnetic carrier particles by agitator in an agitating part so as to form two component type developer. The device for feeding toner has a rotatable feeding roller disposed above the agitating part of said developing apparatus for feeding toner thereto, the feeding roller including plural magnets therein so that magnetic carrier particles are attracted to form magnetic brush around the circumference of the feeding roller and toner is conveyed by the magnetic brush with the rotation of the feeding roller. Between the agitating part and the feeding roller, there is provided a partition having an opening positioned beneath the feeding roller so that the magnetic brush passes across the opening and the conveyed toner drops into the agitating part through the opening. At one side of the periphery of the opening, there is provided a prevention plate for preventing toner leakage, and at another side of the periphery of the opening opposite to the one side, there is provided a regulating plate for regulating a height of said magnetic brush.

Abstract: A copying machine for reproducing an image with toner on a recording sheet. The copying machine has a photoreceptor to hold a latent image corresponding to the image on its surface, in which the surface is charged to a predetermined electric potential before holding the latent image. The latent image is developed with toner, transferred onto the recording sheet, and fixed on the recording sheet with heat. The heater of the copying machine heats up the fixing unit to a predetermined temperature, and terminates heating the fixing unit when an operation of the machine is ended. The copying machine has a capability to detect a temperature of the fixing unit and determining an interval between the time when the operation is ended and the time when the operation is restarted, based on the determined temperature of the fixing unit.
