Abstract:
A recording apparatus for recording an image on a recording medium, comprising:a recording head having a plurality of recording elements for recording an image by utilizing heat;pulse generating means for generating a driving pulse train consisting of a number (m) of pulses including a number (m-1) (m-1)>2) of preheating pulses each having a pulse width (a) and including at least first and second preheating pulses, and one main driving pulse having a longer pulse width (b) than the pulse width (a) of said preheating pulses, the intervals between said pulses in the driving pulse train being equal and each not less than (a.times.(m-1)+b); anddriving means for dividing said plurality of recording elements into multiple blocks, and driving said recording elements in units of blocks to perform recording in such a manner that just before the second preheating pulse of the driving pulse train for one block, with the second preheating pulse being applied after the first preheating pulse of the driving pulse train for the one block, the driving pulse train for the next block is started.
