Abstract

A method for improving functions of an imaging apparatus comprises: replacing a mechanically damaged or aged part whose function is unrecoverable in an imaging apparatus with a new part with the same function and the same structure; substituting a charging roller (22) for a corona wire (22a); substituting a fixing film (41) having an electronic ceramic heating structure (411) for a fixing roller (41a) having a heating tube structure; and reducing the fixing temperature by adopting a low temperature fixing toner, and setting the fixing temperature to a range of 100°C to 140°C.

Description

technical field [0001] The invention relates to an improvement method of an electrophotographic imaging device, in particular to a method for comprehensively improving the functions of an electrophotographic imaging device. Background technique [0002] Electrophotographic imaging equipment includes laser printers and laser copiers. Laser printers or laser copiers use the physical and chemical principles of light, electricity, and heat to output text or images. The basic imaging process can be divided into seven steps: charging, exposure, development, transfer, fixing, cleaning, and power elimination. First, the surface of a photosensitive drum in an electrophotographic image forming apparatus is charged by a corona wire. The laser scanner emits modulated laser light containing image information to the photosensitive drum, and forms an electrostatic latent image corresponding to the image to be formed on the surface of the photosensitive drum. Next, toner from the develope...
