Abstract
A recording apparatus for recording input image data on a recording medium includes: a buffer memory for storing a plurality of lines of input image data as recording data; a recording section which can record on the basis of the recording data at different speeds; and a speed storage section storing a plurality of recording speeds at which recording is performed by the recording section, one of the recording speeds stored in the speed storage section being selected as the recording speed for the recording section in accordance with the amount of recording data stored in the buffer memory. That is, when the amount of recording data stored in the buffer memory is larger than a predetermined number of lines .alpha..sub.1, uniform-speed recording is performed at a first recording speed, and when the amount has become smaller than the number of lines .alpha..sub.1, uniform-speed recording is performed at a second, slower recording speed. When, afterwards, the amount of recording data in the buffer memory has become larger than a second predetermined number of lines .alpha..sub.2 (>.alpha..sub.1), the recording speed is switched back to the first recording speed, at which uniform-speed …
