MANUFACTURE OF ELECTROPHOTOGRAPHIC IMAGE FORMING MEMBER

PURPOSE: To provide an improved production method for continuously producing an photosensitive image forming member having allowable electric properties by rapidly correcting product batch-to-batch variation in electric properties of the member, particularly variation in background potential and also to provide a device for the production. CONSTITUTION: In this improved production which comprises further coating a web coated with a charge generation layer, with a charge transport layer contg. a dopant, the required dopant concn. is detected and the amounts of a high-doped charge transport layer composition and an undoped or low-doped charge transport layer composition, both of which are required to obtain charge of this dopant concn, are determined, and then, the respective determined amounts of the high-doped charge transport composition and the undoped or low-doped charge transport layer composition are supplied to a mixing zone and rapidly mixed together to prepare a uniformly doped charge transport layer composition and, thereafter, the charge generation layer is coated with the resulting charge transport layer composition.
