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. 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 the pigment contained in 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 lower viscosity at 25° C. than a corresponding one of inks to be precedently ejected.

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 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 sheet feed section, an image forming section, a partition unit, an air inflow portion, a first sheet conveyance section, a second sheet conveyance section, and an air sucking and discharging section. The partition unit partitions an interior of an apparatus casing into a first space in which the image forming section is disposed and a second space in which the sheet feed section, the first sheet conveyance section, and the second sheet conveyance section are disposed. Air outside the apparatus casing is taken into the first space through the air inflow portion. The second sheet conveyance section includes a conveyance guide disposed downstream of the image forming section in a conveyance direction of a recording sheet. The air sucking and discharging section sucks air around the conveyance guide and discharges the air into the second space or out of the apparatus casing.

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, and a negative pressure applying section. The recording head ejects ink onto a recording medium. The conveyance section conveys the recording medium placed on a conveying surface thereof to the recording head. The negative pressure applying section includes an airflow chamber and causes the recording medium to be sucked onto the conveying surface by negative pressure through holes in an upper wall of the airflow chamber and holes in the conveying surface. Negative pressure applied through first holes in a first region is greater than that applied through second holes in a second region. The first region is located upstream of a head facing region in a conveyance direction of the recording medium. The second region is located downstream of the first region in the conveyance direction of the recording medium and includes the head facing region.

Abstract: An inkjet recording apparatus includes memory, a processor, an image forming section, and a bending mechanism. The memory stores therein bending information in which a plurality of bending amounts corresponding to respective ejection amounts of an ink ejected from the image forming section are defined. The processor sets a bending amount of a sheet to be conveyed. The bending mechanism includes a roller and a belt that hold the sheet therebetween, and bends the sheet by moving a position of a center of the roller toward the belt based on the set bending amount. The processor calculates for each of areas of the sheet an amount of the ink ejected to the area, and sets the bending amount of the sheet based on the bending amounts corresponding to the calculated amounts of the ink ejected to the respective areas in the bending information.
