Disclosed is a photoconductive toner comprising as a main component a photoconductive substance dissolved or dispersed in a binder resin medium, wherein when the photoconductive substance is a p-type semiconductor, it is combined with a binder resin having a positive tribochargeability and when the photoconductive substance is an n-type semiconductor, it is combined with a binder resin having a negative tribochargeability.

Photoconductive toner

A method for the formation of images comprising: (1) feeding a photoconductive toner, having a particle diameter of on the average 6 .mu.m or less, to a conductive substrate to form a toner layer of 1 to 8 layers on said conductive substrate, (2) uniformly charging said toner layer, and (3) exposing said toner layer to form an electrostatic latent image thereon corresponding to the original.
