Abstract:
An ink jet recording apparatus comprising:an ink jet recording head having a plurality of ink ejection outlets to effect recording on a recording material;a carriage for mounting said ink jet recording head, said carriage being reciprocable relative to the recording material;wherein said ink jet recording head is one of a plurality of ink jet recording heads detachably mountable to said carriage and has an information set portion for providing information about a number of ejection outlets of said ink jet recording head and an interval of the ejection outlets, and energy generating elements for generating energy contributable to eject the ink through said ejection outlets;feeding means for feeding the recording material; anda control circuit for controlling said feeding means and said recording head to control an amount of feeding of the recording material by said feeding means and timing of ink ejection by said recording head, relative to the distance of movement of said carriage, based on the number of the ejection outlets and the interval of the ejection outlets of the ink jet recording head mounted on said carriage, wherein a unit amount of feeding of the recording material is a common divisor of products of the numbers of the ejection outlets and the intervals of the ejection outlets of said respective ink jet recording heads mountable to said carriage, or a product of the common divisor and a reciprocal of any integer.
