Abstract
The utility model relates to a cleaning device for the charging roller in the electronic photography image forming apparatus. The utility model is provided with a support which is fixed with the axial line of the charging roller in parallel. The support is fixed with an elastic base which is axially parallel with the charging roller and protrudes toward the radial direction of the charging roller. The protruding end of the elastic base is fixed with a flexible brush body which is contacted with the surface of the charging roller. As the brush body replaces the elastic strip, the contact area is increased with the charging roller, and the cleaning effect on the charge roller is relatively improved. The elastic base causes the flexible brush body and the charging roller surface to keep the favorable contacting and the contact area as large as possible.
Description
Technical field
The utility model relates to the cleaning device of charging roller in the electrophotographic imaging forming apparatus.
Background technology
Usually electrophotographic imaging forming apparatus such as duplicating machine or laser printer form latent image according to view data on the surface of photosensitive drums, then with image imaging on medium.The cartridge structure of imaging device and principle of work are referring to Fig. 1, the toner 6 of containing carbon dust in one and powder feeding roller 8 being housed is arranged usually, toner 6 has a meal outlet, meal outlet is provided with a developer roll 9, also have one and make the uniform powder delivery cutter 7 of developer roll cloth powder, powder feeding roller 8 is delivered to developer roll 9 with carbon dust, developer roll 9 is delivered to carbon dust on the photosensitive drums 1 that has latent image again, after miscellaneous parts such as photosensitive drums 1 and transfer roll are finished imaging, scrape off the carbon dust that remains in photosensitive drums 1 surface by cleaning doctor 2, and with residual powder income waste powder hopper 5, afterwards, photosensitive drums 1 at its surface charging, is prepared the work of following one-period through charging roller 3.For obtaining image quality preferably, the surface of charging cleaning roller 3 is also extremely important, the method that cleaning blade 4 is set is arranged in the prior art, cleaning blade 4 is axially to add a flexure strip at charging roller 3, the free margins of flexure strip is pressed on the outside surface of charging roller 3, thereby removes the carbon dust of pickup on the charging roller 3.Because flexure strip is that line contact with charging roller 3 surfaces, the removing effect is relatively poor, thereby has influence on the charging effect to photosensitive drums 1, causes that bottom ash is arranged on the image forming medium, defective such as vertical gray line.
Summary of the invention
The purpose of this utility model provides a kind of preferably charging roller cleaning device of cleaning effect.
For this reason, the charging roller cleaning device structure that the utility model provides is as follows, a support of fixing with the charging roller parallel axes is arranged, be fixed with on the support and the charging roller axially parallel, to the elastic foundation that charging roller radially protrudes, the protruding end of elastic foundation is fixed with the flexible brush body that can contact with the charging roller surface.Owing to adopted brush body to substitute flexure strip, increased the contact area with charging roller, can improve cleaning effect relatively to charging roller.Elastic foundation can make Flexible brush body and charging roller surface keep excellent contact and big as far as possible contact area.
Description of drawings
Fig. 1 is the structural representation of a prior art cartridge;
Fig. 2 is the structural representation that the utility model provides cartridge;
Fig. 3 reflects that the A of charging roller cleaning device structure among Fig. 2 is to enlarged drawing;
Fig. 4 is the upward view of Fig. 3.
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
Referring to Fig. 2, the label identical with Fig. 1 represented identical implication among Fig. 2, be that powder feeding roller 8 is housed in the toner 6, toner 6 has a meal outlet, meal outlet is provided with a developer roll 9, also have one and make the uniform powder delivery cutter 7 of developer roll cloth powder, powder feeding roller 8 is delivered to developer roll 9 with carbon dust, developer roll 9 is delivered to carbon dust the photosensitive drums 1 that has latent image again, after miscellaneous parts such as photosensitive drums 1 and transfer roll are finished imaging, scrape off the carbon dust that remains in photosensitive drums 1 surface by cleaning doctor 2, and with residual powder income waste powder hopper 5, this example substitutes existing elasticity chip cleaning device with charging roller cleaning device 10.
Referring to Fig. 3, Fig. 4, on the support 101 of original fixedly photosensitive drums cleaning doctor 2, fix an elastic foundation 102 with double faced adhesive tape, its material is a sponge, free margins at sponge is stained with brush body 103 again with double faced adhesive tape, the brush body material is a felt, and sponge laterally will have enough length what Fig. 3 showed, to guarantee flexibly to compress brush body 103 on charging roller after support 101 is installed on the cartridge.Adopting double faced adhesive tape to fixedly connected between sponge and support, felt, is to consider as the replacing of consumable accessory hairbrush, sponge facility more, simultaneously, is contained on the support also more smooth, not yielding.
