摘要： A developing device includes a casing having a sleeve chamber, an upper chamber and a lower chamber, a developing sleeve housed within the sleeve chamber with a portion of the outer peripheral surface spaced a distance from a photoreceptor drum to define a developing station, and a screw feeder operatively housed within each of the upper and lower chambers. A partition wall separates the upper and lower chambers from each other and has a port defined in a downstream end with respect to the direction of conveyance of the developing material within the lower chamber for placing the upper and lower chambers in communication with each other. A plurality of magnets are accommodated inside the developing sleeve so as to extend in a direction longitudinally of the developing sleeve while positioned circumferentially of the developing sleeve. A weak magnetic pole is disposed at a region confronting the screw feeder within the lower chamber and a strong magnetic pole is disposed at a region corresponding to the port in the partition wall member and longitudinally of the weak magnetic pole.

摘要： An image forming apparatus having replaceable or exhaustible component parts is provided with a security system to determine the authenticity and remaining service life of the component parts. The component part can be provided with an identifiable code, for example, stored in a RAM that can be checked with predetermined identification codes in a computer system in the image forming apparatus. Verification of the authenticity of the replaceable component part can govern the operation of the copying apparatus. The component part, for example, can be provided with a manufacturer code and a confidential identity code. This manufacturer code can be compared with the stored manufacturer code, and a determination can be made as to whether the product is authentic and the remaining useful life of the product. If the product is not authentic, the copying apparatus can be disabled. Also, if the product has been rebuilt or has come to the end of its useful life, the copying apparatus can be disabled.
