IMAGE FORMING APPARATUS AND POWER SUPPLYING METHOD THEREOF

摘要

An image forming apparatus includes an image forming part that forms an image on a recording medium and includes a plurality of photoconductors, a plurality of charging parts that charges the photoconductors, a plurality of developing parts that develops the charged photoconductors, and a plurality of static electricity erasing parts that erases surface potentials of the charged photoconductors. A power supplying part supplies power to the image forming part, and a controller controls to switch the operation of the static electricity erasing parts independently and controls the image forming part to form the image on the recording medium if power applied to the respective photoconductors through the charging parts and the developing parts reaches a target value.
