Description
Technical field
The present invention relates to a kind ofly in the electrophotographic image forming technology, to be used to realize to duplicate, print, the information processing device or the device of function such as fax, relate in particular to a kind of restraining barrier of containing the organic photoconductor of macromolecular material.
Background technology
Early stage optical conductor is to adopt aluminium as substrate, substrate surface plates the inorganic light-guide material of one deck by vacuum coating method, as zinc paste (ZnO), selenium (Se), selen-tellurjum alloy (SeTe), selen-tellurjum arsenic alloy semiconductor materials such as (SeTe:As), thus the inorganic optical conductor of formation single-layer type.Because there are some inadequate natural endowments in inorganic optical conductor, shortcoming such as big as product toxicity, that film formation time is long, cost is high, kind is few, therefore in the later stage eighties, progressively replaced inorganic optical conductor by avirulence, performance is good, cost is low, numerous in variety organic photoconductor.Organic photoconductor can be divided into single-layer type and multi-layered type structure.At present, mainly occupy an leading position by the organic photoconductor of function divergence type sandwich construction.Mainly include charge generating layers (Change Generation Layer, below also can be called for short " CGL ") and charge-conduction layer (ChangeTransportation Layer, below also can be called for short " CTL ") in the organic photoconductor of sandwich construction.On base material, plate or coat above-mentioned charge generating layers and charge-conduction layer respectively, the generation of carrying out photo-generated carrier separates with the stratiform of transfer function, to improve the photoelectricity quantum efficiency and the serviceable life of optical conductor, above-mentioned base material mainly adopts the aluminum or aluminum alloy material to make.Afterwards optical conductor electrophotographic image forming technology was applied to laser printing based on modulating lasering beam, the digital duplicating, fax is printed with collection, duplicate, faxes etc. are multi-functional in the device of one, only find optical conductor by substrate/charge generating layers (CGL)/charge-conduction layer (CTL) is formed, in serviceable life, charge stability, also there is weakness the anti-image aspect of interfering, and then adopt and carry out oxidation processes on the aluminium substrate surface, form one deck restraining barrier (Blocking Layer, below also can abbreviate " BL layer " as), to adapt to the needs of device of new generation, but because the anodized complex process on aluminium base surface, impurity or fault are difficult to eliminate, technique controlling difficulty is higher, processing cost is bigger, difficult requirement and the development that adapts to market, and then found a kind of technology and method of alternative anodization layer, promptly plate the film that layer of even is made of organic material at substrate surface.Conventional plated film restraining barrier (BL) material mainly comprises macromolecule filming material and powder packing material, also can only be made of macromolecular material sometimes.The method that this employing is directly filmed on aluminium base surface, but both stable chargings can cover the flaw of substrate surface again, therefore, have not only simplified numerous and diverse anodic process, but also can greatly reduce manufacturing cost.But also there are some problems in this optical conductor with the restraining barrier of pbz polymer material: as after applying restraining barrier (BL), must toast immediately and solidify, otherwise can pollute charge generating layers (CGL) coated solution that carries out subsequently, this has just caused certain degree of difficulty to the composition of technology and production equipment; In addition, some coating or coating also can stored charges in stable charging, thereby residual charge is progressively increased, and then influence the image output quality; On the other hand, the restraining barrier after the thermal treatment (BL) is with a little less than charge generating layers (CGL) interface that applies subsequently combine, thus the stronger interface potential barrier of formation, thereby be unfavorable for the migration of electric charge carrier, perhaps formed film is poor to the charging charge acceptance.In addition, under certain conditions, also can cause the interface light interference phenomena, thereby influence the quality of image.
Summary of the invention
For overcoming the shortcoming on above-mentioned optical conductor restraining barrier (BL), the invention provides the novel restraining barrier of a kind of optical conductor with the pbz polymer material, the formula materials on this novel restraining barrier (BL) can directly be coated in aluminium, aluminium alloy, other metal or other has the substrate material surface of electric conductivity, restraining barrier after the coating can be without oven dry, and directly plates charge generating layers (CGL), charge-conduction layer (CTL) respectively on its surface; After being coated with the optical conductor surface charging on this restraining barrier, can make charging charge keep stable, can in the suitable time, effectively discharge again, allow relevant electric charge carrier suitably move and pass through, not form higher rest potential; Can form certain roughness on the surface of coating film in addition, make incident beam carry out diffuse reflection, not form light interference phenomena; Can also form adhesion preferably with the charge generating layers (CGL) of back.
The technical solution adopted for the present invention to solve the technical problems is: a kind of optical conductor is used the novel restraining barrier of pbz polymer material; include macromolecule filming material and ultra-fine material with carbon element in the restraining barrier of this substrate surface; macromolecule filming material can be by tygon; polypropylene; polystyrene; polyamide; polyvinyl alcohol (PVA); polyvinyl imidazole; polyethers; polyacrylic acid; nylon; epoxy resin; phenolics; alkyd resin; polyurethane; polymethacrylate; carboxymethyl cellulose; polyglycol; polyoxyethylene; poly; hydroxypropyl cellulose; starch derivative; xanthans; polyvinylpyrrolidone; one or more materials in the macromolecular materials such as polycarbonate are formed; ultra-fine material with carbon element can be by ultra-fine carbon nanoparticle (CarbonNanoparticles); carbon nano-tube (Carbon Nanotubes); powdered graphite; carbon black particle or their handled thing; derivant; one or more materials in the aggregation are formed, and the weight ratio of macromolecule filming material and ultra-fine material with carbon element can be between 40%～99.99% scope.
The invention has the beneficial effects as follows that can make optical conductor can both obtain bigger improvement and raising at aspects such as manufacturing process, image output, staies in grade, manufacturing cost is reduced, and can also regulate the color background of coating in addition, obtains different visual effects.
