发明名称 Image forming apparatus
摘要 An image forming apparatus includes an image bearing member (1) for bearing an electrostatic image; developing means (4) for developing the electrostatic image on the image bearing member with toner electrically charged to a predetermined polarity; transfer means (5) for transferring the toner image from the image bearing member to a transfer material (P); and an image bearing member charging means for contacting to the image bearing member carrying the toner charged by the toner charging means to electrically charge the image bearing member to the same polarity as the predetermined polarity, the image bearing member charging means being effective to reduce a charge amount of the residual toner having passed the toner charging means; a toner charging means (7) for electrically charging residual toner remaining on the image bearing member to the same polarity as the predetermined polarity, the toner charging means being disposed downstream of the transfer means and upstream of an image bearing member charging means (2) with respect to a movement direction of the image bearing member; a scattering member (8) for scattering the residual toner image, the scattering member being disposed downstream of the transfer means and upstream of the toner charging means with respect to a movement direction of the image bearing member.
