a recording apparatus using full - line type ink jet recording heads needs a large amount of electrical power for ink ejection due to a large number of nozzles of the recording heads . therefore , a power supply capacity of the recording apparatus needs to be increased , resulting in increase in an overall apparatus cost . when simultaneously recording on plural recording media using a recording apparatus having recording heads with different electrical power consumptions arranged in a transfer direction of the recording media , recording is performed so that the recording heads to be simultaneously driven are combined so as to be a combination of the recording heads with different electrical power consumptions .
