摘要： PROBLEM TO BE SOLVED: To solve such a problem that it is difficult to reduce the maximum electric power consumption by averaging the power consumption while preventing a decrease in productivity.SOLUTION: With respect to image data which is arranged for each discharge timing, a proportion of the number of nozzles (print ratio) which are simultaneously driven for each discharge timing is calculated from discharge tone data for each discharge timing and the number of discharge nozzles. A control profile of a conveyance speed of a sheet 10 is generated by using a movement average or the like so that it may not exceed the maximum value of the speed specified in the apparatus, by using the stored print ratio. The conveyance of the sheet 10 is controlled on the basis of the generated control profile. The sheet position is detected and timing signals for allowing the nozzles of recording heads 41 to discharge droplets are generated.
