Abstract
An ink jet recording apparatus comprises a plurality of ink discharge portions having discharge ports for discharging ink, ink channels communicating to the discharge ports, and electricity-heat converters for applying the heat energy to the ink within the ink channels, which electricity-heat converters are divided into plural groups supplied with separate signals for generating heat energy, and a conveying mechanism for conveying a recording medium to be recorded with the ink discharged from the discharge ports. The shapes of the ink discharge ports or other geometrical properties of the apparatus are changed for different groups of electricity heat converters to compensate for variations in the velocity of the ink discharged from the different groups.
