PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of conveying a recording paper sheet without causing sagging and pulling between the paper sheets even when two conveying rollers driven by two different motors respectively are synchronized to convey the recording paper sheet.SOLUTION: In an image forming apparatus, CPU 171 performs synchronous control of a motor driver part 173 and a motor driver part 176 so that a stepping motor 190 is driven by a driving signal synchronized with a rotation signal of a DC brushless motor 188 when the same recording paper sheet is conveyed at same timing by using a fixation roller 16a and a paper ejection reversing roller 21, and performs switching to asynchronous control of the motor driver part 173 and the motor driver part 176 so that the driving signal for the DC brushless motor 188 and the driving signal for the stepping motor 190 become independent signals respectively when the different recording paper sheets are conveyed at different timing. |
