Abstract:
1. An image forming apparatus, comprising: a recording head including a first head module and a second head module, each of the first and second head modules having a plurality of recording elements arranged to perform a recording operation with respect to a recording medium, the first head module being arranged in a first orientation on the recording head, the second head module being arranged in a second orientation on the recording head, the second orientation being rotated from the first orientation; a scanning device configured to move the recording head and the recording medium relatively to each other to scan the recording medium with the recording head; a signal processing device configured to select, from print data for one page, print data to be used in one recording operation respectively for the recording elements, and to arrange the selected print data in a prescribed recording element sequence for each of the first and second head modules regardless of the first and second orientations of the first and second head modules; a data transfer device configured to transfer the arranged print data for each of the first and second head modules; and a recording operation control device configured to control the recording operation of the recording elements in accordance with the transferred print data, wherein the recording elements are arranged in a two-dimensional matrix arrangement on the recording head; the scanning device is configured to move the recording head and the recording medium relatively to each other to scan the recording medium with the recording head in a sub-scanning direction; the signal processing device includes: the data transfer device is configured to transfer the print data stored in the second line memory for each of the first and second head modules; wherein the second line memory is configured to read out, of the print data for the one page, the print data in a data region corresponding to the first head module from the image buffer memory in a first read-out direction, and the print data in a data region corresponding to the second head module from the image buffer memory in a second read-out direction reverse to the first read-out direction.
