Abstract

A toner for developing electrostatic latent images containing 0.5 to 5 parts by weight of a salt forming compound represented by the formula <CHEM> wherein R1 is C1- C8 alkyl or benzyl, R2 and R3 are each C1- C18 alkyl, R4 is C1- C18 alkyl or benzyl, X is hydroxyl or amino, and Y is hydroxyl or hydrogen and is not hydrogen when X is hydroxyl, and 100 parts by weight of a resin. The invention also relates to the use of the toner for color electrophotography. The toner provides the advantage of retaining its chargeability over a long period of time.
