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

Embodiment Construction
[0031] Examples of powder feed rollers:
[0032] Reference image 3 , image 3 It is a partial exploded view of the powder feed roller 3 on the fixed end. The powder feeding roller 3 includes an iron shaft core 31 extending along the axis L1. The shaft core 31 is sleeved with an annular sponge 32 extending along the axis L1. The sponge 32 has an end surface 321 on one side thereof. The radius of the end surface 321 is For R1. The powder feed roller 3 also includes a support 4 made of plastic, rubber or copper sheet. Since the support 4 is made of plastic, rubber, copper sheet or stainless steel, the hardness of the support 4 is greater than that of the sponge body 32. . The annular support 4 is a sheet extending along the axis L1. The support 4 is provided with a through hole 41 along the axis L1. The radius of the end surface 42 of the support 4 is R2, and the radius R2 of the end surface 42 is set The ratio is smaller than the radius R1.

The invention provides a powder feeding roller and a processing box. The powder feeding roller includes a shaft core and a sponge body fitted on the shaft core. The powder feeding roller also includes a support piece fitted on the shaft core. The outer part and connected with the sponge body, the hardness of the support is greater than the hardness of the sponge body, the process box includes the shell, the developing roller and the above-mentioned powder feeding roller, the shell surrounds a cavity for containing consumables, and one end of the cavity is provided with consumables At the outlet, the developing roller is installed in the cavity close to the outlet of the consumables, and the powder feeding roller is installed in the cavity adjacent to the developing roller, which avoids the decline in cleaning performance caused by the collapse of the end and effectively improves the cleaning performance of the powder feeding roller and the processing box. Effectively improve the printing quality.
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 installed with the powder feeding roller. Background technique [0002] Image imaging equipment is a device that uses electrophotographic imaging principles to form images on recording materials. Image imaging equipment includes copiers, printers, and fax machines. There are generally two types of process cartridges used in image forming equipment. One is an integrated process cartridge that includes a developing roller and a photosensitive drum as a developing device, and the other is a separate process cartridge that separates the photosensitive drum. Both types of process cartridges are detachably installed in the main body of the image forming apparatus. [0003] A typical image imaging device is a laser printer. The laser printer is currently one of the most widely used image imaging devices....
