Abstract
A color image forming method is disclosed. The following steps are repeated; the steps for forming a latent image on a photoreceptor and developing the latent image by a developer to form a color toner image on the photoreceptor; collectively transferring the color toner image onto an image support; and fixing the transferred toner image; and a toner having a variation coefficient of the shape coefficient of not more than 16% and the number variation coefficient in the number particle diameter distribution of not more than 27% is employed.
Claims11
An electrostatic photographic image forming method comprising steps of;
- forming a first color image on a photoreceptor by a method comprising the steps of forming a latent image corresponding to the first color image on the photoreceptor and developing the latent image by a developer containing a toner having the first color;
- forming another color image on the photoreceptor having the first color image by a method comprising the steps of forming another latent image corresponding to another color image and developing the latent image by a developer containing a toner having another color;
- transferring the color images formed on the photoreceptor to an image support;
- and
- fixing the transferred toner image,
- wherein each of the toner having the first color and the toner having another color contains a resin and a colorant, and comprises toner particles having a variation coefficient of the shape coefficient of not more than 16% and the number variation coefficient in the number particle diameter distribution of not more than 27%.
