发明名称 Electric charge devices for an image forming apparatus
摘要 An image forming apparatus includes an image bearing member for bearing an image, a recording material bearing member for bearing a recording material, a first charge supplying device for supplying an electric charge having a predetermined polarity onto an opposite side of a surface on which the recording material is borne by the recording material bearing member in order to electrostatically transfer the image on the image bearing member to the recording material, and a second charge supplying device for supplying an electric charge onto an opposite side of the surface on which the recording material is borne by the recording material bearing member prior to the recording material is borne by the recording material bearing member, wherein, in a direction substantially perpendicular to a recording material conveying direction, the second charge supplying device supplies an electric charge to the intermediate transfer member in such a way that a charge amount of a second area outside a first area becomes greater than a charge amount of the first area in which the recording material is borne by the recording material bearing member toward the predetermined polarity of the electric charge supplied by the first charge supplying device.
