Abstract

A process cartridge comprises a photosensitive drum (30), a development device (40), a powder transfer roller (50), and an electronic module (26). The photosensitive drum (30) and the development device (40) contact axially. The electronic module (26) comprises a first voltage stabilizing circuit that performs voltage stabilization on a filtered electrical signal and then outputs the processed signal to the development device (40) and a second voltage stabilizing circuit that performs voltage stabilization on a filtered electrical signal and then outputs the processed signal to the powder transfer roller (50), the absolute value of an output voltage value of the first voltage stabilizing circuit being smaller than the absolute value of an output voltage value of the second voltage stabilizing circuit.

Description

technical field [0001] The present invention relates to a process cartridge for an image forming apparatus and a retrofit method for retrofitting an existing process cartridge into such a process cartridge. Background technique [0002] Image imaging equipment is a device that uses the principle of electrophotographic imaging to form images on recording materials. Image imaging equipment includes copiers, printers, fax machines, and the like. A process cartridge used in an image forming apparatus is a unit cartridge including at least a developing roller and a photosensitive drum as developing means, and is detachably mounted in a main body of the image forming apparatus. [0003] A typical image imaging device is a laser printer, which is one of the most widely used image imaging devices at present. A laser printer uses the physical and chemical principles of light, electricity, and heat to output text or images on paper and other media. The basic working process It can be...
