<P>PROBLEM TO BE SOLVED: To provide an image forming apparatus with a high-quality printout having a well-cleaned image carrier surface with no attached matter thereon and thereby causing no dots on an image. <P>SOLUTION: An image carrier is rotated at least once or more during the non-image formation period in a state where a transfer bias is controlled so that an image carrier surface potential in a rotational direction upstream of cleaning means has a reverse polarity to a developer. <P>COPYRIGHT: (C)2012,JPO&INPIT |
