Abstract
In an electrophotographic image-forming method to be practiced in an electrophotographic image-forming system including a halogen lamp light source, an optical system, a cylindrical photosensitive member, a main corona charger, an electrostatic latent image-forming mechanism, a development mechanism containing magnetic toner, a transfer sheet feeding mechanism, a transfer charger, a separating charger, a transfer sheet conveying mechanism, a cleaning mechanism and a charge-removing light source which is capable of adjusting an image-forming process speed, the improvement comprises: using an amorphous silicon light receiving member which comprises a substrate and a light receiving layer disposed on said substrate, said light receiving layer comprising a first layer capable of exhibiting a photoconductivity, a second layer capable of supporting a latent image and a third layer capable of supporting a developed image being laminated in this order on said substrate, said first layer being formed of an amorphous material containing silicon atoms as a matrix, and at least one kind of atoms selected from the group consisting of hydrogen atoms and halogen atoms, said second layer being formed of an amorphous material containing silicon atoms as a matrix, carbon atoms, atoms of an element belonging to Group III of the Periodic Table, and at least one kind of atoms selected from the group consisting of hydrogen atoms and halogen atoms, and said third layer being formed of an amorphous material containing silicon atoms as a matrix, carbon atoms and at least one kind of atoms selected from the group consisting of hydrogen atoms and halogen atoms; and using a fine particle insulating toner having a volume average particle size in the range of 4.5 to 9 .mu.m.
