Abstract

A toner for electrostatic latent image development of the present invention includes toner particles containing toner mother particles and an external additive. The external additive contains fatty acid metal salt particles, and a volume based particle diameter (size) distribution of the fatty acid metal salt particles has two peaks on a side of smaller size and a side of larger size, respectively. A volume based mean particle diameter of the fatty acid metal salt particles having the peak on the side of smaller size is 3.0 μm or smaller and a volume based mean particle diameter of the fatty acid metal salt particles having the peak on the side of larger size is larger than a volume based mean particle diameter of the toner mother particles.

Description

technical field [0001] The present invention relates to a toner for developing an electrostatic latent image, a method for producing a toner for developing an electrostatic latent image, and an electrophotographic image forming method using the toner for developing an electrostatic latent image. Photoreceptor, uneven wear of cleaning blade, toner for developing electrostatic latent image which can obtain good image without shortening life of cleaning blade, method for producing the toner for developing electrostatic latent image, and use of the electrostatic latent image A method of forming an electrophotographic image with a toner for developing a latent image. Background technique [0002] Conventionally, in an electrophotographic image forming apparatus, a lubricant is supplied to the surface of an electrophotographic photoreceptor to reduce the frictional force between the surface of an electrophotographic photoreceptor (hereinafter also simply referred to as "photorecep...
