Abstract
Prompt ink-temperature control can be performed without increasing the capacity of a power supply. In an ink-jet recording apparatus performing recording by causing an ink-jet recording head for performing recording by discharging ink to perform scanning on a recording medium, the temperature of ink is raised to a predetermined temperature by applying a pulse so short as not to cause ink discharge to a discharge heater for discharging the ink, and using a sub-heater for heating the ink. Parameters (short-pulse conditions) of a short pulse to be applied to the discharge heater are changed in accordance with the states of operations of a carriage motor for causing the recording head to perform scanning, and a sheet feeding motor for conveying the recording medium.
