Abstract
A toner for developing an electrostatic latent image on a photoreceptor, wherein the toner includes particles, and wherein the particles of the toner having particle diameters within a range of D±d and measured in &mgr;m, wherein d≦2 &mgr;m, have an average non-electrostatic adhesion force Fne(D) and measured in nN against the photoreceptor, and wherein a proportional factor K of a primary regression line of a diagram in which the toner particle diameter D is plotted on the horizontal axis and the non-electrostatic adhesion force Fne(D) is plotted on the vertical axis, is from 0.01 nN/&mgr;m to 5 nN/&mgr;m.
