Description

Technical Field

[0001] The utility model relates to the technical field of selenium cartridges, in particular to a selenium cartridge which is easy to clean. Background Art

[0002] The toner powder in the toner drum is the key to imaging during the printing process. The toner drum is a cylinder coated with organic material on the surface. It is pre-charged. When light is irradiated, the irradiated part will react with resistance, and the data signal sent controls the emission of the laser. The light scanning on the surface of the toner drum keeps changing, so that some places are irradiated, the resistance becomes smaller, and the charge disappears, while some places are not irradiated by light and still retain the charge. Finally, a latent image composed of electric charges is formed on the surface of the toner drum. The toner powder in the toner drum is a kind of charged fine resin particle. The charge of the toner powder is opposite to the charge polarity on the surface of the toner drum. When the charged toner drum surface passes through the ink roller, the charged part adsorbs the toner particles, thus turning the latent image into a real image.

[0003] During the operation of the printer, the sponge roller provides toner to the developing roller. The toner on the developing roller will automatically be adsorbed to the positively charged position of the charged OPC drum, and the toner on the developing roller that is not adsorbed by the OPC drum will be cleaned by the sponge roller as the developing roller rotates. In the existing technology, since the sponge roller itself adsorbs a lot of toner, there is a situation where the residual toner on the developing roller is not completely cleaned, the powder layer on the surface of the developing roller becomes thicker, resulting in excess toner adhering to the OPC drum, which in turn affects the printing effect.
