Abstract: The light emitting portions 140 are mounted on the substrate 120, and emit neutralization light. The first end engagement portion 115 is engaged with the first end portion 121 of the substrate 120 opposite to the image carrier 2. The partitioning member 130 is connected to the housing 110, so as to form an opened portion that is opened to face the surface of the image carrier 2. The plurality of restriction protrusions 150 are arranged along an axial direction of the image carrier 2. The first end engagement portion 115 is disposed in the central portion of the plurality of restriction protrusions 150 in the arrangement direction. The arrangement direction of the plurality of restriction protrusions 150 curves, such that a central portion of the restriction protrusions in the axial direction is closer to the image carrier than end portions of the restriction protrusions in the axial direction.

Abstract: A control portion makes a recording head perform flushing processing every time a flushing area that does not overlap a recording medium faces the recording head but makes the recording head perform no flushing processing when a flushing area that at least in a part of it overlaps a recording medium faces the recording head. The longer a non-flashing period between the previous and present sessions of flushing processing, the larger the control portion makes the amount of ink ejected by each of nozzles in the present session of flushing processing.

Abstract: A cleaning device includes a separation and contact mechanism that separates a web from a conveyance roller and brings the web into contact with the conveyance roller, and a controller. The controller includes a conveyed sheet number determination unit and a separation and contact control unit. The conveyed sheet number determination unit monitors a conveyed sheet number of both-surface image forming sheets where image forming processing is applied to both a first surface and a second surface with respect to the sheets conveyed by the conveyance roller, and determines whether or not a cumulative value of the conveyed sheet number has reached a predetermined threshold value. The separation and contact control unit controls the separation and contact mechanism so as to allow the web to be pressed to the conveyance roller by a pressing roller when the cumulative value of the conveyed sheet number has reached the threshold value.

Abstract: A cleaning device includes a cleaning unit, a movement mechanism, and a positioning portion. The cleaning unit includes a cleaning part that has a contact surface extending along an axial direction of a conveyance roller and cleans the conveyance roller, and a cleaning housing that supports the cleaning part. The movement mechanism moves the cleaning unit between a cleaning position and a mounting and removing position. The movement mechanism allows the cleaning part to be brought into contact with the conveyance roller at the cleaning position, allows the cleaning part to be disposed below the conveyance roller in a separated manner at the mounting and removing position and allows the cleaning unit to be mounted on or removed from the apparatus body. The positioning portion restricts a relative position between the cleaning part and the conveyance roller by being brought into contact with the cleaning unit.

Abstract: A cleaning device includes a controller configured to control cleaning of a conveyance roller by a web. The controller includes a take-up control unit and a web end determination unit. The take-up control unit controls the solenoid such that the web is taken up by rotatably driving the take-up roller in a state where the web is pressed to the conveyance roller. The web end determination unit determines whether or not an end of the web is exposed on a support roller by a take-up operation of the take-up roller. The web end determination unit determines that the end of the web is exposed on the support roller when a detection result of a detection unit is not changed in spite of a fact that supplying of electricity to the solenoid is performed.

Abstract: A sheet guide of an image forming apparatus includes a first upstream guide member and a first downstream guide member. The first upstream guide member includes an upstream front guide surface and an upstream rear guide surface. The first downstream guide member includes a downstream front guide surface and a downstream rear guide surface. The downstream front guide surface intersects with an imaginary plane formed by extending, toward a downstream side in a conveyance direction of a sheet, the upstream rear guide surface. The upstream front guide surface intersects with an imaginary plane that is formed by extending, toward an upstream side in the conveyance direction, the downstream rear guide surface. When viewed from a direction perpendicular to the upstream rear guide surface, an edge portion of the first upstream guide member on the downstream side is inclined with respect to a width direction perpendicular to the conveyance direction.

Abstract: An inkjet recording apparatus includes a control section, a conveyance section, a recording head, a negative pressure applying section, a gap forming section, and a first voltage applying section. The conveyance section conveys a recording medium placed on a conveying surface. The negative pressure applying section applies negative pressure to holes in the conveying surface to suck the recording medium onto the conveying surface. The gap forming section forms a narrow gap, with the conveying surface, further upstream in a conveyance direction of the recording medium than the recording head. The gap forming section is composed of at least a part of a conductive portion. The first voltage applying section applies a voltage to the conductive portion. The control section controls the first voltage applying section to apply the voltage to the conductive portion while the inkjet recording apparatus performs a specific process.

Abstract: An inkjet recording apparatus includes a recording head, a conveyance section, a plate member, and a negative pressure applying section. The recording head ejects ink onto a recording medium. The conveyance section conveys the recording medium to a position of image forming by the recording head and has a conveying surface on which the recording medium is to be placed. The plate member is located upstream of the recording head in a conveyance direction of the recording medium to form a narrow gap with the conveying surface of the conveyance section. The negative pressure applying section applies negative pressure to the narrow gap. A distance across the narrow gap in a direction perpendicular to the conveying surface is set so as to allow air flowing into the narrow gap from surrounding space to have a higher flow velocity in the narrow gap than before flowing into the narrow gap.
