Powder feeding roller and processing box

Abstract

The invention provides a powder feeding roller and a processing box. The powder feeding roller comprises a shaft core and a sponge body sleeved on the shaft core and a supporting piece sleeved on the shaft core, wherein the supporting piece is arranged at the outer side of the end part of the sponge body and is connected with the sponge body; the hardness of the supporting piece is greater than that of the sponge body, the processing box comprises a shell, a developing roller and the powder feeding roller, wherein the shell defines a cavity body for containing a consumable; one end of the cavity body is provided with a consumable outlet, the developing roller is arranged in the cavity body and is close to the consumable outlet, and the powder feeding roller is arranged in the cavity body and is adjacent to the developing roller. The powder feeding roller and the processing box provided by the invention have the advantages that a situation that the cleaning property is reduced due to collapse of the end part is avoided, the cleaning properties of the powder feeding roller and the processing box are effectively improved, and a line printing quality is effectively improved.

Description

technical field [0001] The invention relates to a powder feeding roller and a processing box, in particular to a powder feeding roller with good cleaning performance and a processing box equipped with the powder feeding roller. 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. Process cartridges used in image forming equipment are generally divided into two types, one is an integral process cartridge including a developing roller as a developing device and a photosensitive drum, and the other is a split process cartridge that separates the photosensitive drum to the outside. Both process cartridges are detachably mounted into the main body of the image forming apparatus. [0003] A typical image imaging device is a laser printer. Laser printers are one of the most widely used image imagi...

AI Technical Summary

Problems solved by technology

[0011] It can be seen that the collapse of the sponge 164, 166 will cause the sponge body to be unable to closely contact with the rubber body 122, and even cause the sponge body 162 to be unable to contact the rubber body 122, so that the cleaning performance of the powder feeding roller 16 will decrease, which in turn will cause the powder feeding roller 16 to be damaged. The end of the developing roller 12 cannot be cleaned at the end, black edges or bottom dust appear on the printed paper pattern, which affects the printing quality
