PROBLEM TO BE SOLVED: To prevent the flocculation and the blocking of toner and to hold a state that the toner is uniformly dispersed by providing a rotatable toner storing body in parallel with the rotary shaft of a photoreceptor and providing an aperture part along a rotary shaft on the surface of the toner storing body. SOLUTION: In this toner cartridge 1, the photoreceptor 2 is uniformly electrified by an electrifier 21 on which voltage is impressed and exposed from a laser, etc., so as to form an electrostatic latent image. The toner 6 passes through a supply roller 32 from the aperture part 41 of the toner storing body 4 and is made a uniform thin layer on a developing roller 31 by a thin layer forming member 9 and also electrified by friction, then the toner is attached to the electrostatic latent image formed on the surface of the photoreceptor 2 by electric field, whereby the image is developed. The toner storing body 4 is rotatably provided in parallel with the rotary shaft of the photoreceptor 2 at a position above a developing chamber 3, and the aperture part 41 is provided along the rotary shaft on the surface of the toner storing body 4. A cover member 42 slidably coming in contact with the toner storing body 4 is provided on the outer periphery of the toner storing body 4 so as to make a part opposed to the chamber 3 open. |
