Abstract:
An ink jet recording apparatus of a line-recording-head type includes one or more recording heads using the same ink and performs recording of an image by conveying a recording medium using multiple passes through a recording region of the recording head while the recording medium is repeatedly conveyed backward and forward to speed up recording and improve image quality. A recording head is controlled to provide that an amount of ink applied to a recording medium in a case where the recording medium is conveyed at a first speed is smaller than an amount of ink applied to the recording medium in a case where the recording medium is conveyed at a second speed higher than the first speed in both of a case where the recording medium is accelerated and a case where the recording medium is decelerated.
