摘要： PURPOSE:To obtain excellent rising characteristics of electrification, charge amt., stability for a long time, environmental stability, and stable property as a toner product by incorporating at least one kind of specified compd. in the toner. CONSTITUTION:The toner contains at least one kind of compd. having orthohydroxy sulfone structure expressed by the formula. In the formula, A is a substituted phenyl group having hydroxyl group at ortho position, B is the same substituent as A, a substd. or unsubstd. aryl group, substd. or unsubstd. alkyl group, or substd. or unsubstd. aralkyl group. In this case, the compd. expressed by the formula acts as an electrification controlling agent and has good solubility with a binder resin. The toner containing this compd. has high specific electrification amt. and good stability for a long time. Thereby, even the toner is stored for a long time, it can give a sharp and stable picture image for electrostatic recording. Since the toner has colorless negative electrification performance, a black negative electrification toner and color toners can be produced.

摘要： PURPOSE:To obtain a toner good in humidity resistance and stability with the lapse of time by incorporating at least one kind of a specified compound. CONSTITUTION:The toner contains at least one kind of the compound represented by formula I in which X is -SO2- or -C(CH3)2-. The toner containing this compound is obtained by kneading a mixture of this compound and a colorant and a binder resin with a heat kneader with the resin melted, and pulverizing the cooled and solidified mixture into 3-20mum particle diameter. This compound is prepared by brominating 4,4-dihydroxydiphenylsulfone. It acts as an electric charge controller and it is colorless and negatively or positively chargeable and well compatible with the binder resin.
