Fig. 8 is to use shaft component 52 to replace the stereographic map of the conductive rollers 51 of shaft component 12 shown in Figure 2, and Fig. 9 is the stereographic map of shaft component 52.Shaft component 52 comprises hollow tube-shape body 53 and metal shaft 56.Hollow tube-shape body 53 is provided with the stiffening rib 55 that radially extends internally from outer peripheral face.In addition, constitute hollow tube-shape body 53 by being connected to each other a plurality of cylindrical members 54 along its length.Thus, hollow tube-shape body 53 comprises a plurality of cylindrical members 54 and is cut apart along its length, so, compare with the situation of traditional integrally formed product that form by metal tube and resin, the length of each member shortens, and therefore, not only can improve machining precision, and can make the handling ease of each member, help boosting productivity.
In the radial center of hollow tube-shape body 53, arrange the metal shaft 56 of passing the hollow tube-shape body, the radial inner end of stiffening rib 55 is supported by metal shaft 56, therefore, can strengthen the rigidity of roller, to increase its bending strength.
Be used to make cylindrical member 54 interconnected parts to be not particularly limited, but structure shown in Figure 10 can be used as example, can carry out combination by the assembling between its end.Graphic cylindrical member 54 has protuberance 62 and rotation stops pin 63 (Figure 10 (a)) in one end thereof 61A side, has recess 65 and rotates stop aperture 66 (Figure 10 (b)) in its another end 61B side.Figure 10 (c) is the cut-open view of cylindrical member 54.Can by rotate cylindrical member so that protuberance 62 be assembled in the recess 65 and make rotate stop pin 63 be assembled to rotate in the stop aperture 66 in, among the end 61B that end 61A is assembled to be in relative status, make cylindrical member 54 combinations securely mutually respectively with this structure.Because be to use roller under rotating, so the link between the member preferably has the anti-locking mechanism of rotation.And, protuberance 62 and recess 65 are carried out taper processing, in graphic cylindrical member 54, to position (positioning).
In the present invention, shaft component 52 shapes own are not particularly limited, and can adopt suitable intended shape.For example, in the gear part 57 (referring to Figure 11) that forms on the member corresponding or as the suitably axial region of shapes or the engaged at end after only gear part member and roller main body form such as D cutting shape, the shape of these function parts can be set thus in the end of the length direction of shaft component 52 with component ends on the length direction.Therefore, can obtain following advantage: separately use axle or carry out complicated axle processing to become unnecessary, and the location of function part becomes easy.
In addition, the profile of shaft component 52 is not limited to the cylindrical shape shown in Fig. 9 etc., but can have drum (crown) shape that the end from length direction as shown in figure 12 increases towards the central part diameter.Under the situation of traditional integrally formed product that constitute by metal tube and resin, the normally straight barrel shape of the profile of roller main body, because the thickness in the time of need forming or grind elastic layer 3 or 4 formation (impregnating) of control coating layer in order to the mould of higher production cost preparation is so be difficult to the processing enter portion diameter drum shape bigger than end diameter.In the present embodiment, hollow tube-shape body 53 is divided into a plurality of members along its length, to reduce the difficulty of processing of each member, therefore, can easily handle drum shape etc., also can guarantee machining precision well.And the quantity that constitutes the member of roller main body is not particularly limited, and can consider to come suitably to determine from aspects such as intensity, saving costs.
As the material that forms hollow tube-shape body 53, can use identical materials with previous explanation in shaft component 2.For example, as metal shaft 56, can use aluminium, stainless steel of resulphurized carbon steel, nickel plating or zinc etc.

When the compound that solidifies by the ultraviolet ray irradiation was used as the resin that constitutes elastic layer 3, at shaping stage, ultraviolet initiator was comprised in the compound, was used to promote resin solidification reaction beginning.
When carbon-based conductive agent is used as the conductive agent of the electric conductivity that is used to control elastic layer 3, the ultraviolet ray that is used to solidify irradiation may be hindered by conductive agent and can not arrive the back side of layer, therefore, ultraviolet initiator can not be given full play to its function, and curing reaction can not fully carry out.

If desired, in compound, except conductive agent, also comprise reaction diluent by ultraviolet ray or electronic beam curing.
Because directly contact with photoreceptor, layering scraper plate etc. or use elastic layer 3,, specifically, make it be no more than 20% so, also preferably make the permanent compression strain as much as possible little even hardness is set at low-level via coating layer 4 indirect contacts ground.
As mentioned above, elastic layer 3 is made of ultraviolet curing resin or electronic beam solidified resin.That is to say that it is to make drying steps useless to reduce equipment cost that elastic layer 3 does not use mould formation, its purpose of design by coating composition.For this reason, need to use the coating of solvent-free or low solvent, and can only solidify by ultraviolet ray or electron beam irradiation.In this case, the viscosity of coating must uprise.
Therefore, as the method that forms elastic layer 3, need to adopt and to have the method for this full-bodied coating with the high precision coating.For this reason, foregoing mold pressing rubbing method becomes preferably.
The following describes coating layer 4.Coating layer 4 can be made by various resins, but considers and can reduce equipment cost, is preferably made by ultraviolet curing resin that contains conductive agent and ultraviolet initiator or the electronic beam solidified resin that contains conductive agent.As the method that forms coating layer 4, preferably: will be applied to by the coating that above-mentioned resin is made on the side face of the conductive rollers that is provided with elastic layer 3, apply coating layer to form, then, apply coating layer by irradiating electron beam or ultraviolet curing, can not need to be used to form the mould and the drying equipment of coating layer 4 thus.
Figure 16 (a) is the stereographic map of the conductive rollers in the forming process when forming coating layer 4 by the roller rubbing method, and Figure 16 (b) is the part figure that layer that the axis direction of the conductive rollers from Figure 16 (a) is seen is regulated scraper plate.Roll-coater 80 comprises applicator roll 81 that is immersed in the coating that is stored in the coating case 82 and the roller driving motor 84 that is used for rotating (E direction) applicator roll 81, support to be provided with the conductive rollers 1A of elastic layer 3 simultaneously at two ends by unshowned parts, and when this conductive rollers 1A is formed at and rotates a end in (arrow D) two ends by driving motor etc. with desired speed, whole conductive rollers 1A is shifted along axis direction (arrow F).In addition, ultraviolet irradiation part or electron beam irradiation part 88 fixedly install concurrently with roll-coater 80.

If coating layer 4 is thin layers, then can realizes full solidification, but, can separately be provided for completely crued step when only solidifying when insufficient in this step by irradiation part 78 cured coated coating layer 4R.And, only in this step, finish curing from required degree to later step that shift, thereby can not cause as problems such as distortion in shifting the way.
Axis by making applicator roll 81 is with respect to the axis tilt angle θ of conductive rollers 1A, can prevent the appearance of the disengaging line that forms when spool and roller be arranged in parallel and be separated from each other.In addition, the material scraping plate 86 of regulating the amount of the coating that is drawn by applicator roll 81 is arranged in the roll-coater 80, can be formed on the thickness of the coating coating layer 4R on the conductive rollers 1A thus with degree of precision control.In addition, form intaglio plate shape injustice, can guarantee the amount of the coating that draws thus, also can be applied to the amount of the coating on the shaft component 2 with High Accuracy Control at the side face of applicator roll 81.

When the coating that is kept by recess 81c was transferred on the side face of the conductive rollers 1A in the forming process, transfer amount was subjected to the viscosity influence of coating, but mainly was by the shape decision of recess 81c.Even like this, compare with the situation of using smooth roller, still can on elastic layer 3, form coating layer 4 with higher precision.
In Figure 18, schematically show the example of intaglio printing pattern.The pattern that can mention has in order in lattice type, pyramid type, bias type, tortoise plastron type and the TF type shown in Figure 18 (a)-(e), in these types, preferably uses lattice type, pyramid type and bias type.For example, when using the intaglio printing pattern of lattice type, in order to guarantee thickness accurately, preferred grid density is that 10～300 lattice/inches, the degree of depth are that 20～650 μ m, recess volume are 5～400cm
