<p><P>PROBLEM TO BE SOLVED: To prevent image failure while reducing drive noise in a cleaning sequence. <P>SOLUTION: Process cartridges 103Y-103K are driven by corresponding DC brushless motors 40Y-40K, respectively. In the cleaning sequence carried out after image formation ends, the DC brushless motors 40Y-40K operate according to driving parameters so that acoustic driving noise decreases. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
