ABSTRACT:
An electrostatic charge developing toner composition comprising (i) toner particles containing a low-molecular weight polypropylene wax and/or a low-molecular weight polyethylene wax, having a volume average particle size of from 4 to 9 .mu.m, and an exposed amount (X% by weight) of the wax on the surface of the toner in the range of 40.ltoreq.X.ltoreq.65, and (ii) abrasive fine particles having an average particle size of from 0.5 to 5.5 .mu.m, and an image-forming process using the toner.
By the toner composition, the occurrence of filming with the wax in the toner particles is prevented and images excellent in the development stability with the passage of time can be formed.
