Ink jet recording apparatus and recording method therefor

A recording apparatus comprising:

• a recording medium conveying path;
• recording medium conveying means for conveying a recording medium along said conveying path;
• a recording head, arranged fixedly in said conveying path during recording, for recording on the recording medium as conveyed, said recording head having a plurality of nozzles, wherein a line of the plurality of nozzles is arranged in a width broader than that of the recording medium;
• discriminating means for discriminating a size of the recording medium;
• and
• recording control means adapted for causing said recording head to record an image in a recording area over the recording medium up to a position outside an edge of the recording medium of the size discriminated by said discriminating means, wherein the plurality of nozzles of said recording head for ejecting the ink are arranged for ejecting the ink so that the nozzles straddle the edge of the recording medium, with such allocation that some of the nozzles of the recording head face the recording medium and other nozzles of the recording head do not face the recording medium,
• wherein the image is recorded on the recording medium based on image data stored in a memory, and
• wherein said recording control means is configured to divide the image data, corresponding to a size of an image larger than the size of the recording medium, into a plurality of divisional image data, and change a count value each time a portion of the image larger than the size of the recording medium is recorded, so as to complete the recording of the image larger than the size of the recording medium when the count value reaches a predetermined value.

• wherein the image is recorded on the recording medium based on image data stored in a memory, and
• wherein said recording control means is configured to divide the image data into intervening area image data and trailing edge image data, and increment a count value each time a portion of the trailing edge image data is recorded, so as to complete the recording of the image when the count value reaches a predetermined value.
