Abstract
A toner image is formed while a developing sleeve is rotated in a direction counter to that of an organic photoreceptor at the developing section and a surface layer of the organic photoreceptor contains metal oxide particles which have a number average primary particle diameter of 3 to 150 nm and are chosen from metal of the 3rd or 4th cycle of a periodic table.
Claims15
An image forming method, comprising the steps of:
- forming an electrostatic latent image on a rotatable organic photoreceptor;
- forming a developing brush with a developing agent containing a toner on a rotatable developing sleeve;
- and
- visualizing the electrostatic latent image into a toner image while the developing sleeve is rotated in a direction counter to that of the organic photoreceptor at the developing section by bringing the developing brush in contact with the organic photoreceptor at a developing region;
- wherein a surface layer of the organic photoreceptor contains metal oxide particles which have a number average primary particle diameter of 3 to 150 nm and metal constituting the metal oxide comprises metal selected from metal of the 3rd or 4th cycle of a periodic table.

An image forming method, comprising the steps of:
- (a) forming an electrostatic latent image;
- (b) forming a developing brush with a developing agent containing toner on a developing sleeve;
- (c) visualizing the electrostatic latent image to form a toner image with bringing the developing brush onto the organic photoreceptor while the developing sleeve is rotated in a direction counter to that of the organic photoreceptor at the developing section, and
- (d) transferring the toner image to an intermediate transfer member;
- (e) conducting the steps of (a) through (d) for each of plural different colors so as to superimpose the plural different color toner images on the intermediate transfer member;
- and
- (f) transferring the superimposed different color toner images to a recording material;
- wherein a surface layer of the organic photoreceptor contains metal oxide particles which have a number average primary particle diameter of 3 to 150 nm and metal constituting the metal oxide comprises metal selected from metal of the 3rd or 4th cycle of a periodic table.

An image forming-apparatus, comprising:
- (a) an organic photoreceptor to form an electrostatic latent image thereon;
- (b) a developing device to form a developing brush with a developing agent containing toner on a developing sleeve and to bring the developing brush in contact with the organic photoreceptor at a developing section so as to visualize the electrostatic latent image on the organic photoreceptor to toner image;
- wherein a surface layer of the organic photoreceptor contains metal oxide particles which have a number average primary particle diameter of 3 to 150 nm and metal constituting the metal oxide comprises metal selected from metal of the 3rd or 4th cycle of a periodic table, and the electrostatic latent image is visualized to the toner image while the developing sleeve is rotated in a direction counter to that of the organic photoreceptor at the developing section.
