Title:
ELECTROSTATIC DEVELOPING TONER AND IMAGE FORMING METHOD
Document Type and Number:
Japanese Patent JP3148950
Kind Code:
B2
Abstract:
PURPOSE: To achieve stabilization of image density and suppress contamination generation in performing repeated image formation using integral transfer method in which non-contact developing is carried out using a two-component developer.
CONSTITUTION: An electrostatic developing toner containing resin particles of average grain size [μm] D and inorganic particles of average grain size 50 to 120nm is applied to an image forming method which a multiple of toner image layers is directly transferred onto a transfer material at a time, the resin particles containing at least a coloring agent, and the volume ratio [vol%] (x) of the organic particles to the resin particles being 5.0/D≤(x)≤15.0/D.
