摘要： An image-forming process capable of keeping a high transfer efficiency for a long period of time, reducing the amount of the toner to be recovered and wasted and obtaining stabilized images without causing image quality defects such as density lowering, density unevenness, ghosts, fog, etc., wherein inorganic fine particles contained in a toner transfer from the toner to an electrostatic latent image holder surface and attach thereto, the attached amount of the inorganic fine particles to the electrostatic latent image holder surface is from 1 to 20% as the average occupied area ratio (CAV) in the electrostatic latent image holder surface, and the difference (CMAX−CMIN) of the maximum occupied area ratio and the minimum occupied area ratio of the attached inorganic fine particles in the electrostatic latent image holder surface is not larger than about 5%.

摘要： The toner for developing an electrostatic charge image comprises a colorant, a binding resin and a resin copolymer of aliphatic hydrocarbon and aromatic hydrocarbon having 9 or more of carbon atoms. Preferably, the toner further comprises a wax. The endothermic peak of the wax at DSC is preferably from 70 to 100.degree. C. The petroleum resin copolymer preferably has a ring and ball softening point of from 80 to 170.degree. C., and the binding resin is preferably a polyester resin. The weight ratio of the aromatic hydrocarbon monomer and the aliphatic hydrocarbon monomer of the petroleum resin copolymer is preferably from 99:1 to 50:50.
