Description
Technical field
The invention belongs to the developer field used in laser development equipment, specifically, relate to a kind of developer for M box in CMYK tetra-look laser development equipment.
Background technology
" official document " generally refers to the file that administration is sent out for not specific citizen and tissue system, the rights and duties that this class file is binding to the public, relate to them, the administrative regulation namely alleged by legal language, other with general binding force regulatory documents beyond regulations.
Have employed this official document in a lot of situation of official document of governments at all levels of China, and the color display effect of word in official document and bright red seal all has regulation, the color developing effect of its color is not identical with the color of common red writing.At present, the manufacture method of the official document of standard is mainly or by the spot color printing of printing house, but this spot color printing needs plate-making and printing will reach a certain amount of, and needs to change once file, the file then printed off will cancel, and this just causes the huge wasting of resources.
Electrophotographic image forming comprises laser development equipment as laser printer, copy and all-in-one multifunctional machine etc., and its groundwork process can be divided into charging, exposure, development, transfer printing, fix steps etc.
CMYK tetra-look laser printer is the product of a laser development equipment wherein type, CMYK refers to green grass or young crops, fuchsin (magenta), Huang, black four kinds of colors usually respectively, the color of the official document that common CMYK tetra-look laser printer types goes out and the misalignment of standard official document are very large, and that is common CMYK tetra-look laser printer cannot print official document.OKI Electrics Industry Co., Ltd. of Japan (OKI) is for the demand in this market domestic, and produce a kind of two-color printing of special printing official document, it is the printer that one can only print redness (R) and black (B).Although the color of its official document printed can obtain the accreditation of departments of government, there are some problems in this dedicated printer, and on the one hand, its price is very expensive, generally more than 50,000 yuan; On the other hand, the printer of this type also can only be used for printing official document, and general purposes cannot meet.
Summary of the invention
Fundamental purpose of the present invention is to provide a kind of developer that may be used for the M box of common CMYK tetra-look laser development equipment.
Another object of the present invention is to provide the manufacture method of above-mentioned developer.
Developer for CMYK tetra-look laser development equipment provided by the invention, comprises the binding resin of 86 to 92 parts, the bronze red pigment of 5 to 6 parts and the magenta pigment of 0.1 to 1.5 part by weight.
From such scheme, central scope of the present invention is with bronze red pigment for mass-tone material, with magenta pigment for auxiliary toning colorant, and by rational weight proportion, finally obtains the developer that color developing effect is consistent with standard official document color developing effect.Wherein, the model of bronze red pigment is PR53:1, and magenta pigment does not then specifically limit, and its model can select PR122, PR269 etc., when practical application, and can also the corresponding increase or reduce its proportioning weight according to the form and aspect of magenta pigment chosen.In the application testing of reality, this developer is put in laser printer corresponding to model, such as Ricoh's commercial production type laser printer, after this developer is encased in the M toner cartridge in CMYK tetra-look printer, the official document printed can get the nod.In addition, developer provided by the invention also has a very outstanding advantage, and namely this developer is after being encased in laser printer corresponding to model, and it can also be used for common office picture and text process, this adds increased the versatility of developer, use convenient.
A preferred scheme is, by weight, developer also comprises the release agent of 1 to 5 part.
From such scheme, the major function of release agent plays demoulding effect to developer when fixing, avoids the developer of melting to be bonded on fixing roller.Particularly, release agent can select one or more in Tissuemat E, polypropylene wax, paraffin, Fischer-Tropsch wax, oxidized polyethlene wax, montanic acid ester type waxes, palm wax, microcrystalline wax, rice wax or fatty acid wax.Find after test, when release agent is at 1 to 5 part, stripping result is better.
