Abstract (en)
[origin: EP0690354A2] The method uses a positive charging toner 7 wherein a resin having a trialkylammonio group at the side chain is blended as an electric charge controlling material, in combination with a positive charging photoconductor 1 wherein a single-layer type positive charging organic photosensitive layer is formed on the surface of an electroconductive substrate. Thereby, a good image having a high image density can be formed without causing image fog. <MATH>
