The present invention relates to toner comprising a binder resin and a colorant, wherein the toner is manufactured by a wet-type granulation method using an organic dispersing agent, an aqueous extract liquid having a surface tension of 50 to 72 mN/m at 25&deg; C., the aqueous extract liquid obtained by mixing 1 part-by-weight toner and 50 parts-by-weight distilled water for 1 hour at 80&deg; C.

Toner for developing electrostatic latent image and manufacturing method thereof

This invention relates to a developing method for electrostatic latent images for developing the electrostatic latent images retained on an electrostatic latent image retaining member, comprising

Developing method of electrostatic latent images for full color image

This invention relates to a carrier for developing electrostatic latent images comprising;

Carrier for developing electrostatic latent image

This invention relates to a photosensitive member for electrophotography with a photoconductive layer on an electrically conductive substrate and a surface protective layer on the photoconductive layer, wherein the surface protective layer comprises a ternary polymer of nylon or a multicomponent polymer of nylon having 10% or less in saturated degree of water absorption under 65% of relative humidity at 24.degree. C. The surface protective layer may have protuberances and hollows thereon. The surface protective layer may further comprises an inorganic layer on the photoconductive layer.

Photosensitive member for electrophotography comprising specified nylon

The disclosure relates to a photosensitive member comprising an electrically conductive substrate, a photoconductive layer of a ceramic material, an intermediate layer of an organic high polymer formed on the photoconductive layer and having a thickness of about 0.01 to about 1 micron and an overcoat layer of a ceramic material formed on the intermediate layer. The intermediate layer has a volume resistivity smaller than that of the overcoat layer.
