Abstract
An electrophotographic toner, which is useful in an image forming method in which a toner image, which is formed on a latent image bearing member, is transferred onto an intermediate transfer member and then the transferred toner image is transferred onto a receiving material, including toner particles including a binder resin and a colorant, and a particulate fluorine-containing material.
Claims21
An electrophotographic toner, which is useful in an image forming method in which a toner image, which is formed on a latent bearing member, is transferred onto an intermediate transfer member and then the transferred toner image is transferred onto a receiving material, comprising:
- toner particles comprising a binder resin and a colorant and having a ratio (Dw/Dn) of a weight average diameter (Dw) to number average particle diameter (Dn) ranging from 1.0 to 1.5;
- and
- a particulate fluorine-containing material.
A method of forming an electrophotographic image, comprising:
- providing a toner comprising toner particles having a ratio (Dw/Dn) of a weight average diameter (Dw) to number average particle diameter (Dn) ranging from 1.0 to 1.5 and comprising a binder resin, a colorant, and a particulate fluorine-containing material;
- forming a latent image on a latent image bearing member;
- developing the latent image with the toner to form a toner image thereon;
- firstly transferring the toner image onto an intermediate transfer member;
- secondly transferring the toner image from the intermediate transfer member onto a receiving material;
- and
- fixing the toner image on the receiving material.
