PURPOSE:To ensure stable satisfactory electrostatic chargeability over a long period of time, to well inhibit filming on a photosensitive body and spending on a carrier and to form satisfactory copied images over a long period of time. CONSTITUTION:This toner for developing an electrostatic charge image contains binding resin-based resin particles obtd. by dispersion polymn. and having a phenolic resin deriv. or a copolymer of a vinyl monomer contg. a sulfonic acid group stuck to the surfaces of the particles or contg. a low mol.wt. phenol deriv. or a phosphorus-contg. antioxidant dispersed in the particles. |
