PURPOSE:To uniformize the triboelectrostatic charge quantity between toner particles and to stabilize an image against temp. and humidity changes by incorporating specific phenylene diamine compds. into the toner. CONSTITUTION:At least one kind of the phenylene diamine compds. expressed by formula I-III are incorporated into the toner. In formula I-III, R<1> denotes an aryl group which may have a substituent; R<2> denotes an alkyl group which may have a substituent; R<3>-R<6> denote hydrogen, amino group. The triboelectrostatic charge quantity between the toner particles or between the carriers of the toner and between the toner and a toner carrier such as sleeve in case of one-component developer is thereby stabilized and the stable image which is not affected by the temp. and humidity changes is reproduced. |
