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: A control portion sets, as a control period, a period after arrival, at a position opposite a recording head, of a first recording medium until passage, at the position opposite the recording head, of a last recording medium. The control portion sets nozzles that do not face the recording medium during the control period as first nozzles, and nozzles that face the recording medium during the control period as second nozzles, to make the total amount of ink ejected by each of the first nozzles in flashing processing during the control period smaller than the total amount of ink ejected by each of the second nozzles.

Abstract: When printing is performed on a recording medium of a second size larger than a first size, a control portion, after passage of the recording medium of the first size at a position opposite a recording head before arrival of the recording medium of the second size at the position opposite the recording head, makes the recording head perform preparatory flushing processing in which ink is ejected toward openings from first nozzles that have not been set as target nozzles during printing on the recording medium of the first size but will be newly set as the target nozzles during printing on the recording medium of the second size.

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.

Abstract: A cleaning device includes a cleaning unit which removes foreign matter adhered on a conveyance face of a conveyance member conveying a sheet, by using a belt shaped web; and a unit moving mechanism which displaces the cleaning unit to a cleaning position where the cleaning unit comes into contact with the conveyance face and to a separation position separated away from the cleaning position. The cleaning unit includes a delivery roller delivering the web, a pressure roller bringing the web pressure-contact with the conveyance face and a winding roller winding the web passed the conveyance face. The cleaning unit is tilted such that a cleaning face of the web between the pressure roller and the winding roller faces upward as the cleaning unit is displaced from the cleaning position to the separation position.

Abstract: An inkjet recording apparatus includes an image forming section, a roller, a heat source, a calculator, a determination section, and a controller. The determination section determines to activate the heat source when an ink ejection amount calculated by the calculator is larger than a specific reference amount. When the determination section determines to activate the heat source, the controller activates the heat source. When temperature of the roller is equal to or higher than a specific temperature, the controller controls the image forming section to form the image on the sheet.

Abstract: An inkjet recording apparatus (1) includes an image forming section (40), a decurler (20), a changing section (50), a first calculating section (72), storage (60), a second calculating section (73), and a controller (75). The image forming section (40) ejects ink onto a sheet (S). The decurler (20) bends the sheet (S). The changing section (50) changes a bending amount of the sheet (S). The first calculating section (72) calculates an ink ejection rate (α) to the sheet (S) for each of areas of the sheet (S). The storage (60) stores therein first bending information (62) indicating a first target bending amount (β) of a specific area of the sheet (S) corresponding to the ink ejection rate (α) to the specific area. The second calculating section (73) calculates a second target bending amount of each of the areas. The controller (75) controls the changing section (50) based on the second target bending amounts.
