Abstract:
1. An image forming apparatus comprising: an image bearing member, which moves while bearing a toner image thereon; a transferring member to which a bias of a predetermined polarity is applied to electrostatically transfer the toner image on said image bearing member to a transfer material in a transferring region; a first toner removing member, which removes a toner on said image bearing member; and a second toner removing member, which is provided on a downstream side in a moving direction of said image bearing member, and to which a bias is applied to remove a toner on said image bearing member, wherein when the toner image on said image bearing member is transferred to the transfer material in the transferring region, and when said first and second toner removing members remove a toner remaining on said image bearing member, biases of polarities different from each other are applied to said first and second toner removing members, respectively, and wherein when the toner image on said image bearing member is not transferred to the transfer material in the transferring region, and when said first and second toner removing members remove a toner remaining on said image bearing member, biases of the same polarities are applied to said first and second toner removing members.
