Image forming apparatus

An image forming apparatus, comprising:

• a rotating photosensitive body;
• a charging member rotating while contacting said photosensitive body and uniformly charging a surface of said photosensitive body;
• a cleaning member cleaning a surface of said charging member;
• and
• means for bringing said charging member into contact with said photosensitive body or separating said charging member from said photosensitive body;
• said charging member being rotated while contacting said cleaning member and cleaning said charging member when said charging member is separated from said photosensitive body;
• wherein said charging member is rotated in a direction opposite to a rotational direction of said photosensitive body and is brought into contact with said photosensitive body.

An image forming apparatus comprising:

• a charging member rotating while contacting said photosensitive body and uniformly charging a surface of said photosensitive body;
• a cleaning member cleaning a surface of said charging member;
• and
• means for bringing said charging member into contact with said photosensitive body or separating said charging member from said photosensitive body;
• said charging member being rotated while contacting said cleaning member and cleaning said charging member when said charging member is separated from said photosensitive body;
• wherein a rotational direction of said charging member taken when said charging member is in contact with said photosensitive body is the same as a rotational direction of said charging member taken when said charging member is in contact with said cleaning member.

An image forming apparatus, comprising:

• a rotating photosensitive body;
• a charging member rotating in a direction opposite to a rotational direction of said photosensitive body while contacting said photosensitive body in order to uniformly charge a surface of said photosensitive body;
• a cleaning member cleaning a surface of said charging member;
• and
• a device bringing said charging member into contact with said photosensitive body or separating said charging member from said photosensitive body;
• said charging member being rotated while contacting said cleaning member in order to clean said charging member when said charging member is separated from said photosensitive body;
• and
• a speed reducer reducing a peripheral surface speed of said charging member when said charging member is separated from said photosensitive body so as to become slower than a peripheral surface speed of said charging member maintained when said charging member is rotated contacting said photosensitive body.

An image forming apparatus, comprising:

• a rotating photosensitive body;
• a charging member rotating while contacting said photosensitive body and uniformly charging a surface of said photosensitive body;
• a cleaning member cleaning a surface of said charging member;
• and
• a mechanism bringing said charging member into contact with said photosensitive body or separating said charging member from said photosensitive body;
• said charging member being rotated while contacting said cleaning member and cleaning said charging member when said charging member is separated from said photosensitive body;
• wherein said charging member is rotated in a direction opposite to a rotational direction of said photosensitive body and is brought into contact with said photosensitive body.
