Abstract
An image is formed by using in combination a photoreceptor having a surface roughness Rz not larger than 1.0 and a developing agent comprising a toner containing toner particles containing a binder resin and a coloring agent, silica particles, and a metal soap, the weight ratio of the silica particles to the metal soap falling within a range of between 10 and 60.
Claims13
A developing agent applied to an image carrier having a surface roughness Rz not larger than 1.0, comprising toner containing toner particles containing a binder resin and a coloring agent, silica particles, and a metal soap, the weight ratio of said silica particles to said metal soap falling within a range of between 10 and 60.
An image forming apparatus, comprising:
- an image carrier having a surface roughness Rz not larger than 1.0;
- a developing device arranged to face said image carrier, housing a developing agent comprising toner containing toner particles containing a binder resin and a coloring agent, silica particles, and a metal soap, the weight ratio of said silica particles to said metal soap falling within a range of between 10 and 60, and serving to develop an electrostatic latent image formed on said image carrier so as to form a developing agent image;
- a transfer device for transferring said developing agent image onto a transfer material;
- and
- a fixing device having a heating member and serving to fix the developing agent image transferred onto said transfer material.
