Description
The present invention relates to a kind of manufacture method of electrophotography developing agent.
The world enters the information age, and reprography then is to promote, use and develop one of modern most important information approach.Along with progress of science and technology and development, modern reprography is developed rapidly in more American-European advanced industrial countries, and with other modern office equipment combination, supporting use, brought surprising high-level efficiency.And,, make this high-tech area of reprography almost still blank because basic industries fall behind in China.In recent years, along with China's economic reform, opening and enlivening, seem more and more important as the reprography of information media, the duplicating machine development in market at home is quite rapid, according to the statistics of Tianjin reprography information institute, China's production and marketing situation of duplicating machine in recent years is:
The maximum annual production of homemade complete machine is 2000;
Nineteen eighty-three complete system import amount is 20000;
The duplicating board number that comes into operation in the whole nation:
Surplus nineteen eighty-three 30000;
Surplus 1985 70000;
Nineteen ninety reaches 350000.
According to Beijing Daily on October 5th, 1991, only in Beijing, 40000 of Xeroxs are just arranged, if every machine can both run well, to consume about 100 tons of toner every year.
Above statistical figure show that in recent years, duplicating machine market development at home is swift and violent, and a developer market in great demand forms.Because domestic reprography is quite backward, domestic products can not be used for a large amount of import duplicating machine by the substituting import one toner because electrical property is bad, the developer of dependence on import raw material production makes it nocompetitive on price because the prices of raw and semifnished materials are expensive again, and produces dependence abroad.Therefore, exhaust a large amount of foreign exchanges in order to satisfy the home market needs, as not developing domestic technology as early as possible, along with domestic growing to even greater heights that modernization needs to information approach, the situation of this passive backwardness must also be wanted long-term existence to go down and further increase the weight of country's foreign exchange burden in this respect.
In view of the foregoing, the objective of the invention is to design a kind of quality can match in excellence or beauty with the import developer, and the cheap manufacture method of the colour developer for electrostatic reprography of production domesticization fully.
