Abstract
An electrostatic image developing toner is disclosed. The resin of the toner particle has a cell structure and an average value of FERE-horizontal diameters of the cells is from 20 to 200 nm and a variation coefficient of the FERE-horizontal diameters of the cells is from 10 to 35%.
Claims21
A toner for developing a static charged image containing a toner particle comprising a resin and a colorant, wherein the resin has a cell structure having cells and a cell wall, and an average value of FERE-horizontal diameters of the cells is from 20 to 200 nm and a variation coefficient of the FERE-horizontal diameters of the cells is from 10 to 35%.
An image forming apparatus, comprising:
- a photoreceptor;
- a charging device to electrically charging the photoreceptor;
- an exposing device to imagewise exposing the photoreceptor so that a latent image is formed on the photoreceptor;
- a developing device to develop the latent image with toner so that a toner image is formed on the photoreceptor;
- wherein the exposing to the photoreceptor is carried out by digital exposure.
