Problems solved by technology

However, the existing photosensitive drums are prone to hollow characters, lighter printing colors, or background scattering and grainy backgrounds when printing.
Most of the bad phenomena in the printing process are caused by the poor cooperation between the photoconductive material and the substrate, or the insufficient properties of the photoconductive material itself and the poor cooperation with the substrate.

Abstract

The invention relates to the field of laser printing and consumables thereof, and particularly relates to a photoconductive material for laser printing and a method for preparing a photosensitive drum. The photoconductive material for laser printing is prepared from the following components in parts by weight: 1-5 parts of tungsten carbide powder, 1-3 parts of nickel, 0.5-1.3 parts of phthalocyanines compounds, 1.2-1.8 parts of silicon dioxide, 0.5-0.7 part of silicon and 10-15 parts of resin mixtures. Raw materials of the photoconductive material are well matched with each other, and thus thephenomenon that the photoconductive material has good photoconductivity and good wear resistance can be ensured.

Description

technical field [0001] The invention relates to the field of laser printing and its consumables, and in particular to a photoconductive material for laser printing and a method for preparing a photosensitive drum. Background technique [0002] The photosensitive drum, also known as the toner cartridge, is the core component of the laser printer. It is a photosensitive device, mainly made of photoconductive material. Its basic working principle is the process of "photoelectric conversion". It is used as consumable material in laser printers, and it is relatively expensive. Commonly used photoconductive materials for photosensitive drums are cadmium sulfide (CdS) and selenium-arsenic (Se-As). Organic photoconductive materials (opc) and so on. It is generally composed of a basic substrate made of aluminum and a photosensitive material coated on the substrate. However, the existing photosensitive drums are prone to phenomena such as hollow characters, lighter printing color...
