Abstract
PURPOSE: To enhance the charging characteristics, copying property, and fixing property and to obtain clear and spotless images as a result of the realization of high speed in electronic photography, by the use of a specified toner binder.
CONSTITUTION: 30 to 40 weight % of monomer bodies such as methacrylate glycidyl containing glycidyl group or β-methyl glycidyl group and other vinyl monomer of 60 to 97 weight %, which is capable of being copolymerized, are subjected to copolymerization, whereby a copolymer whose glass transition temperature is 20°C or more is obtained. Then, a bridging compound such as sebacic acid, which contains 2 to 6 functional group of one or more types in one molecule that can react with glycidyl group or β-methyl-glycidyl group included in the polymer at the time of heating, is blended so that ratio between the acamount of the funtional group and the amount of glycidyl group or β-methul-glycidyl group becomes 3 to 30 weight %, thereafter it is heated and mixed.
