The each developing member being cartridge due to imaging device provides different voltage, and has multiple output electric contact, so just requires in the conducting end of cartridge, have the multiple conductive contacts matched with output electric contact.Fig. 1 and Fig. 2 shows existing a kind of cartridge 10, there is box body 11 and developer roll 12, end cap 13 is arranged on an end of developer roll 12 axis, be provided with the support portion 131 of the turning axle supporting developer roll 12, end cap 13 is also provided with the development contact 141 that be connected defeated with the output of imaging device electricity and powder feeding roller contact 151, development contact 141 is connected with the end of the turning axle 121 of developer roll 12 by web member 14 and spring 142, powder feeding roller contact 151 is connected with the turning axle 161 of powder feeding roller by web member 15, web member 14 and 15 separates setting mutually, and be all fixed on by screw on box body 11 with end cap 13.Separate each other due to each conductive contact and be connected with each developing member respectively, causing cartridge conducting end to have more parts and complex structure, thus operation is more when assembling, cartridge cost is higher.
Therefore need that a kind of structure is simple, assembling procedure is few, lower-cost cartridge.
Summary of the invention
Fundamental purpose of the present utility model is to provide that a kind of structure is simple, assembling procedure is few, lower-cost cartridge.
For realizing above-mentioned fundamental purpose, the cartridge that the utility model provides comprises: the box body being provided with the carbon dust accommodation section holding carbon dust; For processing the multiple developing members with developing electrostatic latent image to carbon dust; Be arranged on the conductive contact piece of the conducting end of box body, for from multiple output contact of imaging device to receive different voltage.Wherein conductive contact piece is one-body molded.
From above scheme, conductive contact piece with can multiple output contact of imaging device, and it is one-body molded, thus be respectively the connection of each developing member and separated electric contact and web member without the need to arranging, the parts of cartridge reduce, thus the structure of cartridge is simple, assembling procedure is few and cost is lower.Conductive contact piece connects as one, thus when the output contact of conductive contact piece and imaging device, and the voltage provided for each developing member is the voltage between multiple voltage, still can play the effect making carbon dust charged, can not affect developing process.
More concrete scheme is, conductive contact piece is made up of conductive plastic.From above scheme, conductive plastic is easy to molded, makes conductive contact piece can have required shape and without the need to processing, make the structure of simplification cartridge further and cost-saving.
Scheme is more specifically, and developing member comprises developer roll, and developer roll has from the axially outstanding turning axle of box body, and turning axle is made up of conductive material, and conductive contact piece has the supporting construction of supporting rotating shaft.As seen from the above, conductive contact piece not only can be electrically connected but also support the turning axle of developer roll with developer roll, thus without the need to arranging other structures of the turning axle supporting developer roll on cartridge, the structure of cartridge can simplify further.
Further, turning axle is outside equipped with axle sleeve, conductive contact piece support sleeve.Axle sleeve can be made up of the material that wearing quality is good, prevents conductive contact piece inordinate wear, axle sleeve by conductive contact piece support can make axle sleeve structure simplify and easy for installation.
Further, axle sleeve is made up of conductive material.As seen from the above, conductive contact piece makes developer roll charged by axle sleeve.
Another further scheme is that axle sleeve is made up of insulating material, and conductive contact piece has the part with turning axle ends contact.Make developer roll charged by conductive contact piece and turning axle ends contact.
Preferably, developing member comprises powder feeding roller, and powder feeding roller has from the axially outstanding turning axle of box body, and the turning axle of powder feeding roller is made up of conductive material, and conductive contact piece has the supporting construction of the turning axle supporting powder feeding roller.As seen from the above, conductive contact piece not only can be electrically connected but also support the turning axle of powder feeding roller with powder feeding roller, thus without the need to arranging other structures of the turning axle supporting powder feeding roller on cartridge, the structure of cartridge can simplify further.
Another more concrete scheme is that conductive contact piece is arranged on end cap, and end cap is arranged on conducting end and has the supporting construction supporting the end of at least one in developing member.As seen from the above, conductive contact piece can contact with developing member and not play a supportive role, and is undertaken by end cap the support of developing member end.
