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 cleaning device includes a cleaning unit and a unit moving mechanism. The cleaning unit brings a web into contact with a conveyance member rotating around an axis and removes foreign matter adhered to the conveyance member. The unit moving mechanism displaces the cleaning unit to a cleaning position where the web is brought into contact with the conveyance member and to a separation position where the web is separated away from the conveyance member. When the unit moving mechanism displaces the cleaning unit from the cleaning position to the separation position, the cleaning unit is displaced in a counter direction opposite to a rotational direction of the conveyance member on a contact face between the conveyance member and the web.

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: An inkjet recording apparatus includes an image forming section, a heater, a first calculation section, storage, and a second calculation section. The image forming section ejects ink onto a sheet in which first to M-th regions are defined (M is an integer of at least 2). The heater heats an n-th region of the sheet using an n-th heat source (n is an integer of at least 1 and no greater than M). The storage stores therein temperature information indicating a first heating temperature for the n-th region. The second calculation section calculates a second heating temperature for the n-th region based on the temperature information and the ink ejection amount to the n-th region calculated by the first calculation section.

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.

Abstract: A cleaning device cleans a surface of a sheet conveyance member that conveys a sheet in an image forming apparatus which executes image forming processing, using a liquid recording material. The cleaning device includes a cleaning member having a contact surface configured to be brought into contact with the surface of the sheet conveyance member. A contact angle of the contact surface with the recording material is smaller than a contact angle of the surface of the sheet conveyance member with the recording material.

Abstract: An inkjet recording apparatus includes an image forming section, a heater, a calculation section, storage, and a determination section. The image forming section ejects ink onto a sheet in which first to M-th regions are defined (M is an integer of at least 2). The heater includes first to M-th heat sources and heats an n-th region of the sheet using an n-th heat source (n is an integer of at least 1 and no greater than M). The calculation section calculates an ink ejection rate of ink to be ejected onto the n-th region. The storage stores therein heating information indicating whether it is necessary to heat the n-th region. The determination section determines whether or not to cause the n-th heat source to generate heat.

Abstract: An inkjet recording apparatus includes a control section, a conveyance section, a recording head, a gap forming section, and a negative pressure applying section. The gap forming section is disposed upstream of the recording head in a conveyance direction of a recording medium to form a narrow gap with a conveying surface of the conveyance section. The negative pressure applying section applies negative pressure to the narrow gap. The control section adjusts a distance across the narrow gap in the direction perpendicular to the conveying surface to a first distance in image formation. Upon receiving an instruction to clean the gap forming section, the control section adjusts the distance across the narrow gap in a direction perpendicular to the conveying surface to a second distance that is greater than the first distance and causes the negative pressure applying section to start applying negative pressure to the narrow gap.
