Method and device for developing an electrostatic latent image based on toner amount and image formation system using the developing device

Abstract

A developing method for an image formation system includes the steps of supplying a toner and developing an electrostatic latent image formed on a latent image support of the image formation system with the toner for visualization. A toner amount of a solid area T(g/m.sup.2) has a maximum toner amount per unit area on a recording medium and satisfies the following expression: 1.ltoreq.T/a.ltoreq.1.2 wherein a=(4.pi./3).multidot.(dt/2).sup.3 .multidot..rho.t({(3).sup.1/2 .multidot.dt.sup.2 /2} (g/m.sup.2), where dt is a toner volume center diameter (m) and st is a toner density (g/m.sup.3). A developing device for developing an electrostatic latent image includes toner amount regulation means for regulating a toner amount that satisfies the above expression.
