Patent ID: 7241543

Claim:
An image forming method comprising; developing a latent image on a photoreceptor by a developer containing a toner to form a toner image, wherein the toner comprises at least 65% by number of toner, particles having a shape coefficient of 1.2 to 1.6, and the toner has a variation coefficient of the shape coefficient is 4 to 16%, and a number variation coefficient in number particle size distribution of 8 to 27 percent; and the photoreceptor has a photosensitive layer containing a charge generation material and a charge transfer material, and charge generation material contains a mixture compound represented by Formula 1 in which n has a range of distribution and (x+y) is not more than 99% when x represents the ratio of a component having the largest content and y represents the ratio of a component having the second content, X-(CTM-group) n -Y Formula 1 wherein CTM-group is a charge transfer group; X and Y are each a hydrogen atom, a halogen atom or a mono-valent organic group, X and Y is the same or different; and n is an integer of from 0 to 10, provided that n is 1 to 10 when both X and Y are a hydrogen or halogen atom at the same time.
