Document Type and Number:
Japanese Patent JP6834734
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an image formation method that has an excellent cleaning property, and can form an image of high definition even when a low coverage image is continuously output.SOLUTION: An image formation method according to the present invention has a step and the like that coat a lubricant on a surface of an electrophotographic photoreceptor (photoreceptor drum 41). An electrostatic charge developing-purpose toner to be used in an electrophotographic image formation includes a toner base particle that has an external additive on the surface, and includes at least a silica particle A and a silica particle B as the external additive. The silica particle A is surface-modified in a range where a number average primary particle size is 35 to 75nm, and a particle surface of the particle A is surface-modified by silicone oil. The particle B is surface-modifed in a range where a number average primary particle size is 15 to 30nm, and a particle surface of the particle B is surface-modified by a silazane compound, or an alkoxysilane compound.SELECTED DRAWING: Figure 2
