Claim 0:
1. An ink discharging apparatus comprising:
a conveyor configured to convey a recording medium in a conveying direction;
a head configured to discharge a water-based ink for recording onto the recording medium conveyed by the conveyor;
a heater which is located at downstream in the conveying direction of the head, and which is configured to heat the recording medium or the water-based ink for recording adhered to the recording medium; and
a controller configured to control the conveyor, the head and the heater,
wherein the controller is configured to control the conveyor and the heater so as to control a conveying speed of the recording medium at a facing position at which the recording medium faces the heater so that a cumulative heating amount received per unit area of the recording medium from the heater at the facing position is in a range of 0.7 J/cm2 to 2.9 J/cm2; and
the water-based ink for recording includes:
a resin-dispersed pigment,
resin fine particles,
water, and
a first water-soluble organic solvent of which saturated vapor pressure at 20° C. is in a range of 0.03 hPa to 2.20 hPa, the first water-soluble organic solvent being included in a range of 10% by mass to 40% by mass to an entire amount of the water-based ink for recording,
wherein a content amount of a second water-soluble organic solvent, of which saturated vapor pressure at 20° C. is greater than 2.20 hPa, is less than 3% by mass to the entire amount of the water-based ink for recording; and
a content amount of a third water-soluble organic solvent, of which saturated vapor pressure at 20° C. is less than 0.03 hPa, is less than 10% by mass to the entire amount of the water-based ink for recording.
