The shortcoming of said structure cartridge is: when image forming warning carbon dust surplus was not enough, the actual toner surplus in the toner was not a deficiency, so the carbon dust utilization factor is low, waste resource, contaminated environment.

Summary of the invention

The purpose of this utility model provides the high cartridge of a kind of carbon dust utilization factor.

For achieving the above object, the cartridge that the utility model provides comprises toner, and it is used for the splendid attire carbon dust; Puddle support, it is positioned at toner, and to stir the carbon dust in the toner, puddle support has the single-revolution radius around central shaft rotation; Two light inlet windows are arranged on a pair of outer wall of toner, be respectively applied for light beam that reception sends from light emitting devices in the image forming and with this light beam thoroughly to the optical pickup apparatus of image forming; Wherein, at least one in described two light inlet windows has across the inside surface inside and outside the described turning radius.

The inside surface of two light inlet windows of comprehensive engagement in whipping process of the puddle support in the prior art cartridge, can in time clean the inside surface of light inlet window, therefore light just can two light inlet windows of printing opacity be got back to optical pickup apparatus in the image forming when carbon dust also has certain surplus, thereby image forming alarm carbon dust is used up.And the cartridge of the utility model structure has shortened the length of puddle support, make puddle support in whipping process, only touch the wherein part of a light inlet window inside surface, that is to say, reduced the translucent effect of light inlet window, thereby extended figure former time of fire alarming, also just improved the utilization factor of carbon dust in the toner.

Further technical scheme is:

Described light inlet window adds 15% black toner material by transparent ABS material and makes.

Described light inlet window adds 10% black toner material by glass fibre and makes.

The transmittance of the light inlet window that above-mentioned two kinds of materials are made is all lower, can reduce the translucent effect of light inlet window equally, thereby has further extended figure former time of fire alarming, has improved the utilization factor of carbon dust in the toner.
