发明名称 Image forming apparatus having toner charging members
摘要 An image forming apparatus includes an image bearing member, a first toner charging member, provided downstream of a transfer device and upstream of a charging device with respect to a rotational direction of the image bearing member, for electronically charging toner remaining on the image bearing member, and a second toner charging member, provided downstream of the first toner charging member and upstream of the charging device with respect to the rotational direction, for electrically charging the toner remaining on the image bearing member by being supplied with a voltage of a polarity identical to a normal charge polarity of the toner. In addition, a controller controls application of a predetermined voltage to the first toner charging member, and a first AC voltage is applied to a developer.
