发明名称 Colour image forming apparatus with a phase adjusting device
摘要 <p>The image forming apparatus includes a plurality of rotation members (1a,1b,1c,1d) for bearing respective images, a plurality of motors (40a,40b,40c,40d) for driving and rotating the plurality of rotation members (1a,1b,1c,1d), respectively, a phase detector (49) for detecting phases of the plurality of rotation members (1a,1b,1c,1d), and a phase adjusting device (20) for carrying out adjustment so that phase differences among the plurality of rotation members (1a,1b,1c,1d) have a predetermined relationship, in which the phase adjusting device (20) carries out the adjustment before the motor in rotation is stopped, and stops the motor after completion of the adjustment. Accordingly, a first print time can be shortened without executing an unnecessary phase adjustment sequence after activating motors. Alternatively, after executing and completing the phase adjustment, the motors are stopped. <IMAGE></p>
