Abstract
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 (C ) in the electrostatic latent image holder surface, and the difference (C −C ) 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%.
