A recording apparatus is provided with a droplet discharging head having a nozzle forming portion and a charging unit. The nozzle forming portion includes nozzles formed therein. The charging unit is configured to impart an electrical charge to the medium. The charging unit imparts, to the medium, an electrical charge having the same polarity as an electrically charged state of the nozzle forming portion after the droplets are discharged.

A medium support unit for supporting a medium on which a printing apparatus performs printing includes a support portion having a support surface for supporting the medium, a heating portion heating the support portion, and a main body portion on which the support portion is mounted, wherein heat conductivity of a mounting portion as a portion of the main body portion on which the support portion is mounted is lower than heat conductivity of the support portion.

An inkjet printer includes a first ink head to eject a first ink, and a second ink head to eject a second ink. A generator generates dot groups including at least a first dot group and a second dot group including ink dots of the second ink. The dot groups include all the ink dots of the second ink. A first printing controller forms, on a recording medium, a first printing layer of the first ink and the first dot group. A second printing controller forms a second printing layer of the second dot group, above or below the first printing layer.

An inkjet printer includes an inkjet head configured to perform printing using ink along a main scanning direction onto a print medium by moving in the main scanning direction; a platen configured to support, from an opposite side of the inkjet head, a portion of the print medium being printed by the inkjet head by a printing portion supporting region extending in the main scanning direction; a print heater configured to heat the print medium via the printing portion supporting region; and a fan device extending in the main scanning direction, and configured to blow air out from a blower outlet for blowing the air toward a surface of the portion of the print medium supported by the printing portion supporting region.

A recording method includes applying an ink composition onto a recording medium, primarily drying the recording medium during the application of the ink composition, transporting the recording medium applied the ink composition to a secondary drying device, and secondarily drying the recording medium with the secondary drying device. The variation in surface temperature of the recording medium from the primary drying temperature (T1) to the lowest temperature and the variation in surface temperature of the recording medium from T1 to the highest temperature, in the period from completion of the application of the ink composition to completion of the secondary drying are 40% or more and 370% or less, respectively, relative to T1. The surface temperature of the recording medium is increased to the secondary drying temperature at an average rate of 7 C./s or less after the completion of the application of the ink composition.

An ink jet printer according to an aspect of the invention includes a heat platen that is capable of heating in a state of supporting recording sheets, a head that discharges ink onto the recording sheets from a nozzle plate in which nozzles are provided, a temperature sensor that acquires temperature information of the nozzle plate, a main scanning portion that performs a main scanning operation that relatively moves the head in a main scanning direction with respect to the recording sheets, a sub-scanning portion that performs a sub-scan operation that relatively moves the recording sheets in a sub-scanning direction, which intersects the main scanning direction, with respect to the head, and a determination portion that determines the necessity of a heating operation, in which the heat platen heats the nozzle plate, on the basis of the temperature information before printing.
