Provided are an ink-jet image recorder for recording an image precisely and a method for correction of belt conveyance mechanisms by controlling the roller drive on the basis of fluctuation of the conveyance rate caused by a particular failure in the endless belt. In the belt conveyor mechanism of the ink-jet image recorder, the method for correction of the belt conveyance comprises a position detection step (Step S) for detecting a specified position on the endless belt; a measurement step for measuring the rotation rate of the roller; a position calculation step (Step S) for specifying a position on the endless belt; a calculation step (Step S) for calculating the corrected conveyance rate; in the error-causing region where a conveyance error is caused by the endless belt during movement of the endless belt, by addition to the position of the endless belt, of the amount of correction of the conveyance rate of the endless belt calculated from the conveyance error corresponding to the error-causing region; and a driving rate calculation step (Step S) for adjusting the motor driving rate in accordance with the corrected conveyance rate.
