    Abstract: A transfer device includes a conveyance belt, a transfer roller, a stretch roller, and a cleaning member. The conveyance belt is configured to convey a sheet via a contact position with an image carrier. The transfer roller is configured to transfer the toner image onto the sheet at the contact position. The stretch roller is configured to stretch the conveyance belt at a separation position where the sheet is separated from the conveyance belt and the stretch roller is grounded via a resistance portion having electrical resistance. The cleaning member is provided to oppose the stretch roller across the conveyance belt, downstream, in a running direction of the conveyance belt, from the separation position, and is configured to attract the toner attached to a surface of the conveyance belt upon application of a voltage having a polarity opposite to the charge polarity of the toner.

    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 inkjet recording apparatus includes three or more recording heads. The recording heads contain different inks and eject the different inks sequentially on a recording medium. The different inks each contain a pigment and a polyhydric alcohol monobutyl ether. Of the different inks, an ink to be ejected first has the lowest pigment content ratio. Of the different inks, an ink to be ejected third and an ink to be subsequently ejected each have a pigment content ratio equal to or higher than that of a corresponding one of inks to be precedently ejected. Of the different inks, an ink to be ejected second and an ink to be subsequently ejected each have a polyhydric alcohol monobutyl ether content ratio higher than that of a corresponding one of inks to be precedently ejected.

    Abstract: A cleaning device includes a controller configured to control cleaning of a conveyance roller by a web. The controller includes a separation and contact control unit, a conveyance roller rotation control unit, and a take-up control unit. The separation and contact control unit is configured to control a separation and contact mechanism so as to allow the web to be pressed to the conveyance roller when the conveyance roller is in a non-conveyable state. The conveyance roller rotation control unit rotates the conveyance roller in a state where the web is pressed to the conveyance roller. The take-up control unit is configured to allow the take-up roller to perform a take-up operation of taking up the web by rotatably driving the take-up roller plural times at a predetermined time interval within a cleaning time set in advance in a state where the conveyance roller is being rotated.
