Patent ID: 8184342

Claim:
A recording apparatus comprising: a recording head having a recording element row in which a plurality of recording elements are disposed in a first direction, the recording elements of said row being divided into a plurality of groups each of which comprises a plurality of consecutive recording elements, the recording elements of each group having block numbers different from each other and being driven by time-division driving based on an order of the block numbers; a scanning unit configured to scan the recording head, wherein an image is formed by the scanning unit relatively scanning the recording head a plurality of times with respect to the same area on a recording medium in a second direction intersecting with the first direction; a conveying unit configured to convey the recording medium in the first direction; a storing unit configured to store recording data; an obtaining unit configured to obtain information relating to the inclination of said recording element row relative to said second direction; a reading unit configured to read out reading data from said storing unit, wherein an address of the reading data is different from an address of the recording data of the storing unit by an address corresponding to a correction value determined for each of the groups based on the information relating to the inclination of the element row; a determining unit for determining a starting block number at which the time-division driving is started for each scan based on the information relating to the inclination of the element row and a conveyance amount of the recording medium; and a driving unit configured to drive said recording elements based on the reading data and a driving order starting from the starting block determined by the determining unit.
