Claims

[Claims for Utility Model Registration] 1. A developing roller that electrostatically attracts the toner to the electrostatic latent image formed on the surface of the photoconductor, within the developing device body that accommodates the toner, and toner being supplied to the developing roller. In a developing device equipped with a fur brush having bristles and a toner hopper provided at the upper part of the developing device main body for replenishing toner through an opening communicating with the developing device main body, the periphery of the opening of the toner hopper is , a developing device that is brought into contact with the bristles of a fur brush. 2. A developing device body that accommodates toner is equipped with a developing roller that electrostatically attracts toner to an electrostatic latent image formed on the surface of a photoreceptor, and a fur brush that has bristles that supply toner to this developing roller. At the same time, a toner hopper having an opening communicating with the inside of the developing device main body is provided at the upper part of the developing device main body, and a toner replenishing roller that replenishes toner into the developing device main body by rotation is provided in the opening. A developing device characterized in that the toner replenishing roller is exposed within the developing device main body and brought into contact with bristles of a fur brush.
