Description
Technical field
The utility model relates to the electrophotographic imaging forming apparatus developer box, particularly comprises developer roll and is used for holding the electrophotographic imaging forming apparatus developer box in the powder storehouse of brand-new developer.
Background technology
With handle box 100 be the basic comprising core laser printer and so on electrophotographic imaging forming apparatus, its imaging process is, sees Fig. 1, charged equably by charging roller 102 in photosensitive drums 101 surfaces.Laser scanner 103 contains image information and through the laser beam 104 of ovennodulation to photosensitive drums 101 emission, cylindrical surface in photosensitive drums 101 after laser beam 104 irradiations forms the static charge distribution plan that its distribution has difference, that is the electrostatic latent image corresponding with image to be duplicated.Afterwards, developer roll 105 so by carbon dust 106 spreadings that transmit in the (not shown) of powder storehouse near the photosensitive drums 101 and make on its cylindrical surface that is adsorbed on photosensitive drums 101, after aforementioned electrostatic latent image covering, it is converted to can macroscopic visual image.Along with the rotation of photosensitive drums 101, the visual image that is formed at photosensitive drum surface by carbon dust 106 replaces to the position at transfer roll 107 places.Effect through the entrained transfer voltage of transfer roll 107, the carbon dust of visual image form is transferred on the surface of recording mediums 108 such as paper, with after after the carbon dust of the visual image form on 112 pairs of recording mediums 108 of warm-up mill 111 and backer roll carries out heating and pressurizing, carbon dust is penetrated in the fibrage of recording medium 108, and the visual image that carbon dust is formed for good and all solidifies on recording medium 108.Visual image on the aforementioned photosensitive drums 101 is after being transferred roller 107 transfer printings, and residual carbon dust 109 attached to it is struck off by useless powder scraping blade 110, and stores up in waste powder hopper.So just finished a basic imaging workflow.This flow process is the result of cycle operation repeatedly, just can obtain the needed image of printing person.
Above-mentioned handle box 100 is as the basic comprising core of laser printer and so on electrophotographic imaging forming apparatus, and its basic comprising part mainly comprises photosensitive unit and developing cell.Photosensitive drums 101 shown in Figure 1 and charging roller 102 are main composition bases of photosensitive unit, and developer roll 105 and powder storehouse are the main composition bases of developing cell.In addition, be used for removing, store up the useless powder scraping blade 110 of residual carbon dust 109 and waste powder hopper, together be arranged on the support frame of photosensitive unit usually also as the ingredient of photosensitive unit.The conveying mechanism (not shown) of the laser scanner 103 among Fig. 1, transfer roll 107, warm-up mill 111, backer roll 112 and recording medium 108 is set at the main frame inside of electrophotographic imaging forming apparatus usually.Constitute the photosensitive unit of handle box 100 and developing cell and can be used as an integral body and concentrate and be arranged on the support frame of handle box 100, obtain the integrated relatively product of function; Also can be arranged to independently photosensitive unit and developing cell respectively, obtain the single relatively product of function, and with electrophotographic imaging forming apparatus in conjunction with the time be assemblied in correspondence position in the electrophotographic imaging forming apparatus main frame respectively.Wherein, the developer box of bearing the developing cell task need pass through assembling process when producing.In assembling process, transmit gear and the toner seal member will be pre-formed in being mounted to one by one on the framework of developer box on the basis of developer box framework in the powder storehouse as the developer roll 105 of developer box accessory, carbon dust puddle support, carbon dust reserves mechanism for monitoring, rotary torque.Yet existing developer box is of a great variety, and its framework presents different characteristics.In finishing the assembling process of above-mentioned developer box, need the suitable positioning seat of many its shapes and developer box frame shape to fix the developer box framework.This reduces production cost of products for the automatic batch production of developer box, and it is totally unfavorable to enhance productivity.
Summary of the invention
At the problems referred to above, the utility model purpose is to provide a kind of electrophotographic imaging forming apparatus developer box, this developer box can adapt to the single positioning seat of its structure in assembling process, thus reduce developer box because of its frame shape change to the positioning seat shape propose than high selectivity.
For achieving the above object, the electrophotographic imaging forming apparatus that the utility model proposes comprises the powder storehouse that is used to hold brand-new developer with developer box, be used for stirring and carry the developer that the powder storehouse holds puddle support, be used for the developer spreading that transmits from the powder storehouse in the develop developer roll in district of photosensitive drums.The powder storehouse is surrounded by the framework that is used to support developer box and forms.Framework offers meal outlet corresponding to the position in powder storehouse.Developer roll is set up near the framework of meal outlet.Under developer box was assemblied in state in the electrophotographic imaging forming apparatus, framework was provided with the suitable location division of positioning seat that is used for assembling developer box back to developer roll and the surface that is positioned at the top.
Aforementioned electronic electrophotographic imager developer box, its location division are two, and they lay respectively at framework along the axial both sides of developer roll.
Aforementioned electronic electrophotographic imager developer box, its location division is rendered as surface level under developer box is assemblied in state in the electrophotographic imaging forming apparatus.
Aforementioned electronic electrophotographic imager developer box, its location division are rendered as the groove that extends and be recessed into developer box along the plummet direction under developer box is assemblied in state in the electrophotographic imaging forming apparatus.
Aforementioned electronic electrophotographic imager developer box, its location division are rendered as under developer box is assemblied in state in the electrophotographic imaging forming apparatus along the plummet direction and extend and protrude from rib outside the developer box.
Electrophotographic imaging forming apparatus developer box of the present utility model, cause the defective of needs many moneys positioning seat and its coupling when the assembling developer box because of its frame shape is different at existing developer box, the both sides axial in its framework along developer roll are provided with the location division respectively.The form of plane, groove or rib is adopted in the location division.Under this structural regime, when the formation accessory that developer roll, carbon dust puddle support, carbon dust reserves mechanism for monitoring, rotary torque is transmitted developer boxes such as gear and toner seal member is assembled on the developer box, the operator only needs the location division of developer box is aimed at the support of positioning seat, the location division of plane, groove or rib form is connected on the support of positioning seat, can realize the location of developer box, thereby be convenient to implement follow-up assembly process.The developer box of this structure, because it has adopted unified location division, therefore, only need the positioning seat of a standard to match and just can implement whole follow-up assembly manipulations with it, thus, when having reduced the assembling developer box to multifarious requirements of structural regime such as positioning seat shapes, positioning seat Mould design and production cost have correspondingly been reduced, thereby reduced the production cost of developer box effectively, also made the assemble flow of developer box be able to standardization, helped improving its production efficiency.
