ABSTRACT:
In a transfer type ink jet recording system, a scanning is conducted on a transfer drum using a recording head to form ink dot strings. The recording head is moved in one subscanning direction with a fixed pitch so that ink drops are impacted to positions which are not adjacent to ink dot strings formed immediately before the current scanning step, whereby a repellent phenomenon is prevented from occurring. According to another aspect of the invention, the printing sequence is changed in accordance with the density of print data. A dot counter counts the number of printing dots of each of a plurality of writing blocks in a video memory. A controller decides the sequence of printing the printing blocks on the basis of the result, and transfers information indicative of the sequence of the printing blocks to a memory selector. In deciding the sequence, restriction is set so that adjacent blocks are not successively subjected to the printing step. The memory selector reads out printing data from a video memory on the basis of the sequence information, and transfers the data to a recording head.
