Abstract: An image forming apparatus (1) includes an image forming section (12), an intermediate transfer belt (125), a drive roller (125A), a secondary transfer roller (210), a brush section (80), a cleaning device (70), a power supply device (81), and a ground portion (82). The brush section (80) is disposed at a location downstream of the secondary transfer roller (210) in a direction of travel of the intermediate transfer belt (125) and facing the drive roller (125A) with the intermediate transfer belt (125) in between. A potential difference is applied between the brush section (80) and the secondary transfer roller (210) by the power supply device (81) and the ground portion (82), so that an electric current having the same polarity as a normal charge polarity flows from the brush section (80) through the drive roller (125A) to the secondary transfer roller (210).

Abstract: An image forming apparatus includes: a photosensitive drum; a transfer belt configured to be charged to an opposite polarity to the surface of the photosensitive drum to electrostatically attract a recording paper sheet and convey the sheet while pressing the sheet against the photosensitive drum, thereby transferring a toner image formed on the surface of the photosensitive drum to the sheet; a fixing section configured to apply heat to the recording paper sheet having the toner image transferred thereto and thus fix the toner image on the sheet; a toner collecting member disposed to face a separating position where the recording paper sheet is separated from the transfer belt and extending in a width direction of the sheet being conveyed, the toner collecting member being electrically grounded; and a thermally conductive member configured to collect heat near the fixing section and conduct the collected heat to the toner collecting member.
