A drying apparatus includes: a heat drying section that heats a medium to which a liquid has been applied from a first surface side of the medium; a temperature adjusting section that adjusts a temperature of the medium from a second surface side of the medium, the second surface being on the opposite side to the first surface; and a control section capable of controlling the heat drying section and the temperature adjusting section. The control section controls the heat drying section and the temperature adjusting section individually in accordance with the type of the medium.

A recording apparatus includes an ejecting head that ejects aqueous ink which includes a colorant, polymer particles, water, and an aqueous organic solvent, of which static surface tension is from 22 mN/m to 30 mN/m, and a difference between a value of dynamic surface tension after 10 msec and a value of dynamic surface tension after 1000 msec is greater than 2 mN/m and equal to or smaller than 10 mN/m, when dynamic surface tension is measured with a maximum bubble pressure technique, in an the ink droplet amount in a range of less than 10 pl.

An application device includes a conveyer to convey a recording medium, an application roller to apply a treatment liquid to the recording medium, a pressure roller to sandwich the recording medium with the application roller to press the recording medium against the application roller, and a winding member to form a curved conveying path to have the recording medium curved along a conveying direction to wind the recording medium around the pressure roller. The pressure roller comes in contact with the application roller when applying the treatment liquid and separates from the application roller when not applying the treatment liquid. A predetermined positional relationship is maintained between the pressure roller and the winding member while the pressure roller moves close to the application roller to be in contact with the application roller, or the pressure roller moves away from the application roller to be separated from the application roller.

Systems and methods for adjustable interlacing of drying rollers in a print system. One system is an apparatus that includes first rollers that conduct heat from a heat source, and dry a web of print media as the web travels over a front side of the first rollers in a first direction. A last roller of the first rollers turns the web in a second direction. The apparatus also includes second rollers disposed a distance above the first rollers and that transport the web in the second direction. The apparatus further includes a movement mechanism that reduces the distance between the second rollers and the first rollers to cause the second rollers to occupy spaces between the first rollers so that the web traveling in the second direction contacts a back side of the first rollers to further dry the web.

A drying device for drying a recording medium is provided. The drying device includes a plurality of heating roller units independently detachable from the drying device. The heating roller units includes at least one upstream heating roller unit disposed upstream relative to a conveyance direction of the recording medium and at least two downstream heating roller units disposed downstream relative to the conveyance direction of the recording medium. Each upstream heating roller unit includes an upstream heating roller, two upstream temperature detectors, and two upstream controllers. The upstream heating roller includes two upstream heat sources having different heating areas. The two upstream temperature detectors are disposed at respective end parts of the upstream heating roller, to detect temperatures of the respective upstream heat sources to output signals. The two upstream controllers control the respective upstream heat sources based on the respective signals from the respective upstream temperature detectors.

Methods and devices for creating an electrostatic force. An electrostatic platen device includes a continuous conductive layer; a first dielectric layer provided on a first surface of the continuous conductive layer; and a second dielectric layer provided on a second surface of the continuous conductive layer opposite to the first surface of the conductive layer. A power source is electrically coupled to the continuous conductive layer to generate an electric tacking field.

An image forming apparatus includes an image former to form an image on a sheet; a dryer to dry the sheet on which the image is formed by the image former, a cooler to cool the sheet dried by the dryer, and an inspection unit to inspect the image on the sheet cooled by the cooler, wherein the dryer, the cooler, and the inspection unit are arranged below the image former.

Provided is a dielectric heating apparatus for heating a first ink and a second ink that adhere to a medium. The first ink contains carbon black, and the second ink does not contain carbon black. The dielectric heating apparatus includes: a first electrode unit as an electrode unit configured to heat the first ink and the second ink, the first electrode unit including a first electrode and a second electrode that face the medium; and a first voltage application unit configured to apply an AC voltage having a frequency of 300 MHz or more and 300 GHz or less to the first electrode and the second electrode.

A printer includes a glue belt on which a plurality of different types of media are arranged, an ejection head that ejects ink to the plurality of media while reciprocating along an X-axis direction, a first detection unit that detects an end portion of the medium, a second detection unit that detects a thickness of the medium, and a control unit, and the control unit causes the first detection unit to detect an end portion of each of the plurality of media, sets an ejection range in which the ink is ejected for each medium based on a detection result of the first detection unit, causes the second detection unit to detect a thickness of each of the plurality of media, and determines an adjustment amount for adjusting the landing position of the ink for each medium based on a detection result of the second detection unit, and adjusts the landing position based on the adjustment amount and causes the ink to be ejected in the ejection ranges of the plurality of media from the ejection head.
