Process cartridge for an image forming apparatus

Abstract

A disposing case which is inserted into an imaging device as being demountable is provided with at least one composing element for executing the imaging process and a nonvolatile memorizer (20, 20Y, 20M, 20C and 20K). In the nonvolatile memorizer, the data with same content are memorized in a plurality of mutually distant memorizing units, the quantity of which is rested with the sort of the data.For a plurality of memorizing units used for same data content, the address displacement volume between one memorizing unit and the other memorizing unit is set according to the sort of the data.

Description

[0001] This application is a divisional application of the Chinese invention patent application No. 01125491.2 filed on July 24, 2001, entitled "Processing Box for Imaging Device". technical field [0002] The present invention relates to a process cartridge detachably inserted into an image forming apparatus main body, and having executable image forming process components and a nonvolatile memory storing given information associated with an address. Background technique [0003] In recent years, a process cartridge detachably inserted into an image forming apparatus main body has come into general use with the main purpose of recovering natural resources. In addition to the components necessary to complete the known electrophotographic process, including a photosensitive drum, a charging unit, an exposing unit, a developing unit, a cleaner, and a toner storage, some of these process cartridges also have non-volatile The memory stores information on the respective process c...

Problems solved by technology

[0005] However, the aforementioned constant amount of address shifting brings about an unhelpful increase in address usage, resulting in memory inefficiency

It is inconvenient for the processing box because it is difficult to fit a large memory on it, and considering the cost
