PURPOSE:To maintain high transferring efficiency by using a corona discharger of biased AC. CONSTITUTION:The AC electric field biased at transferring is applied. In a copying machine which uses the one of N type such as, for example, ZnO type, as a photoreceptor 1 developed by the powder developer, the polarity of the developer is +, hence the polarity of transfer corona is -. Transfer is accomplished by the difference between this - component and + component. Thereby, the transfer maintaining high transferring efficiency is accomplished. |
