Abstract: A drying device according to the present disclosure includes a conveying device, an air blowing device, and an exhaust device. The conveying device conveys a medium on which an image is formed, along a predetermined conveyance direction. The air blowing device sends air toward the medium from above the medium conveyed by the conveying device to dry the medium. The exhaust device takes in air above the medium from both sides of the conveying device in a width direction perpendicular to the conveyance direction and exhausts the taken air to an outside.

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 drying apparatus includes an endless conveying belt, a conveying plate, and a suction device. The endless conveying belt has a number of through-holes, and supports the medium and conveys the medium in a predetermined conveyance direction. The conveying plate has a number of through-holes and supports the conveying belt in contact with an inner circumferential surface of the conveying belt. The suction device sucks air through the through-holes of the conveying belt and the through-holes of the conveying plate to attract the medium to the conveying plate. The conveying plate is formed so as to be expandable and contractable in a direction parallel to the conveyance direction.

Abstract: An inkjet recording apparatus includes a conveyance belt, a recording head, a control portion, an interval detection sensor, a thickness detection reference member, and a storage portion. The control portion is capable of executing an interval detection mode, a thickness calculation mode, and a landing timing correction mode. In the landing timing correction mode, the control portion sets the landing timing to be equal to a reference landing timing when the thickness of the conveyance belt stored in the storage portion is equal to a predetermined reference thickness, sets the landing timing to be earlier than the reference landing timing when the thickness of the conveyance belt stored in the storage portion is larger than the reference thickness, and sets the landing timing to be later than the reference landing timing when the thickness of the conveyance belt stored in the storage portion is smaller than the reference thickness.

Abstract: The inkjet recording apparatus includes a conveyance belt, a conveyance plate, a suction unit, an inkjet head, and a cleaning unit. The conveyance belt has a plurality of through holes. The conveyance plate includes a plurality of through holes formed in bottom portions of the plurality of recessed portions. The suction unit is configured to suck the sheet to the conveyance belt. The inkjet head includes a head main body and a head end portion adjacent to the head main body, and faces an upper surface of the conveyance plate via the conveyance belt. The cleaning unit removes ink adhering to a lower surface of the head main body. A depth of the recessed portion in a facing region facing the head end portion of the conveyance plate is shallower than a depth of the recessed portion in a region other than the facing region.

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 fixing device includes a heating roller, a non-contact temperature sensor, a first air channel, and a second air channel. The non-contact temperature sensor detects a temperature of the heating roller in a non-contact manner. The first air channel is located between the non-contact temperature sensor and the heating roller. The second air channel is located at a side of the non-contact temperature sensor that is farther from the heating roller. An air velocity in the first air channel is greater than an air velocity in the second air channel.

Abstract: A drying apparatus includes a conveying device, a heating device, a conveying rollers pair, a driving roller rotation detection part, a driven roller rotation detection part, and a control part. The conveying device conveys a medium in a conveyance direction. The heating device dries the ink of the medium under a high temperature environment. The conveying rollers pair is disposed on a downstream side of the heating device, and includes a driving roller and a driven roller. The driving roller rotation detection part detects a rotating of the driving roller. The driven roller rotation detection part detects a rotating of the driven roller. The control part stops the heating device when the rotating of the driving roller is detected by the driving roller rotation detection part and a rotation period obtained by a detection result of the driven roller rotation detection part is longer than a reference rotation period.
