ABSTRACT:
An electrostatic toner image forming method is disclosed. In the method, the photoreceptor comprises a charge generation layer containing an N-type charge generation material and a charge transportation layer containing a charge transportation material and has a thickness of from 5 to 15 μm; and the toner contains colored particles which have a ratio, Dv50/Dp50, from 1.0 to 1.15 and a ratio, Dv75/Dp75, from 1.0 to 1.20 and the content of particles having a diameter of 0.7×Dp50is not more than 10 in number, and the reversal development is performed under a condition satisfying the following expression;in-line-formulae description="In-line Formulae" end="lead"?50≦|E|≦100 Expression 1in-line-formulae description="In-line Formulae" end="tail"?E: Electrical field intensity applied to the organic photoreceptor during development.
