Embodiment Construction

[0013] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0014] figure 2 is a sectional view of the developer cartridge in the present invention. Such as figure 2 As shown, the developer cartridge in the present invention includes a powder bin 201 for accommodating carbon powder, an agitating frame 202 disposed in the powder bin 201, a developing roller 203 disposed on the other side of the powder bin 201, and a first contact with the developing roller 203. A powder feeding roller 204 and a second powder feeding roller 205 in contact with the developing roller 203 .

[0015] The powder bin 201 has an arc-shaped upper surface 206 and an arc-shaped lo...

Abstract

The invention relates to a developer box, which comprises a powder bin, a stirring rack, a developing roller, a first powder feeding roller and a second powder feeding roller, wherein the stirring rack is arranged in the powder bin; the developing roller is arranged on one side of the powder bin; rotary shafts of the first powder feeding roller and the second powder feeding roller are respectively arranged between the stirring rack and the rotary shaft of the developing roller; and the first powder feeding roller and the second powder feeding roller are arranged at the periphery of the developing roller and contacted with the developing roller. When the flowability of carbon powder is poorer, even though the carbon powder is in short supply, sufficient carbon powder can be supplied to the developing roller due to sequential two-time powder feeding of the first powder feeding roller and the second powder feeding roller, so printing quality is ensured. Moreover, after the second powder feeding roller cleans the surface of the developing roller, the first powder feeding roller can also re-clean the surface of the developing roller, so the carbon powder which is supplied to the surface of the developing roller is always new, and the defects of lines, bottom ashes, light color and the like are overcome.

Description

technical field [0001] The present invention relates to electronic imaging device components, and more particularly, to a developer cartridge. Background technique [0002] In current image forming equipment, such as laser printers and laser copiers, a developer cartridge for developing an electrostatic latent image formed on a photosensitive drum is provided. figure 1 is a sectional view of a developer cartridge in the prior art. Such as figure 1 As shown, the developer cartridge includes a powder bin 101 for accommodating carbon powder. Inside the powder bin 101, an agitating device 104 for stirring and conveying the carbon powder is provided. On the other side of the powder bin 101, developing rollers in contact with each other are provided. 102 and powder feeding roller 103. In the working state, through the agitation of the stirring device, the carbon powder in the powder bin 101 is sent to the powder feeding roller 103 along the wall of the powder bin, and then thro...
