PURPOSE:To obtain the toner which is not stuck to the surface of a photosensitive body and with its fluidity, polarity controllability, developing property and durability enhanced by incorporating a hard powder treated with a specified silane compd. into the toner. CONSTITUTION:A hard fine powder treated with a fluorine-contg. silane compd. expressed by formula I, for example, is incorporated into the toner, hence the toner is not stuck to the surface of a photosensitive body, and an electrostatic charge image developing toner with the fluidity, polarity controllability, developing property and durability enhanced is obtained. In the formula, (m) is an integer of 0-13, (n) is an integer of 0-5, X is hydrogen or fluorine atom and can be the same or different from each other, Y is NH, and R is a 1-5C alkyl or alkoxy group and can be the same or different from each other. |
