Charging device and image forming apparatus

摘要

An image forming apparatus includes a charging device applies a voltage to charge an image bearing member. The charging device is provided with a charging means to which a voltage is applicable to charge said image bearing member, said charging means being provided with a magnetic particle carrying member for carrying and conveying a magnetic particle layer contacting with said image bearing member during the charging operation; a container contains magnetic particles therein; and a replacing device replaces the magnetic particles carried on the magnetic particle carrying member with the magnetic particles contained in the container. A developer develops a latent image produced on the image bearing member by the charging device using a toner to produce a toner image. A transferring device transfers the toner image from the image bearing member simultaneously with developing of the latent image without using a cleaner member after transferring by said transferring device and before charging by said charging device.
