Cleaning apparatus and image forming apparatus

A cleaning apparatus for a photosensitive drum, the cleaning apparatus comprising:

• a cleaning roller that is positioned so as to be in contact with the photosensitive drum;
• a toner layer thickness regulating member that regulates the thickness of a toner layer adhering to the surface of the cleaning roller;
• and
• the toner layer thickness regulating member comprising a toner layer thickness regulating roller that rotates in contact with the cleaning roller,
• wherein an outer diameter of the toner layer thickness regulating roller is not an integral multiple of the outer diameter of the cleaning roller.

A cleaning apparatus for a photosensitive drum, the cleaning apparatus comprising:

• a cleaning roller that is positioned so as to be in contact with the photosensitive drum;
• a toner layer thickness regulating member that regulates the thickness of a toner layer adhering to the surface of the cleaning roller;
• and
• the toner layer thickness regulating member comprising a toner layer thickness regulating roller that rotates in contact with the cleaning roller,
• wherein an outer diameter of the toner layer thickness regulating roller is smaller than the outer diameter of the cleaning roller.

A cleaning apparatus for a photosensitive drum, the cleaning apparatus comprising:

• a cleaning roller that is positioned so as to be in contact with the photosensitive drum;
• and
• a toner layer thickness regulating member that regulates the thickness of a toner layer adhering to the surface of the cleaning roller;
• and
• the toner layer thickness regulating member comprises a metal roller that rotates in contact with the cleaning roller,
• wherein rotation directions of the metal roller and the cleaning roller are the same direction at the point of contact between the two rollers, and
• a ratio (X) of the linear velocity of the metal roller relative to that of the cleaning roller is set such that 0<X≦2.

A cleaning apparatus for a photosensitive drum, the cleaning apparatus comprising:

• a cleaning roller that is positioned so as to be in contact with the photosensitive drum;
• a toner layer thickness regulating member that regulates the thickness of a toner layer adhering to the surface of the cleaning roller;
• the toner layer thickness regulating member comprising one of a foaming body roller or a brush roller that rotates in contact with the cleaning roller;
• and
• the cleaning roller comprising a foaming body roller different from the toner layer thickness regulating member,
• wherein an outermost layer of the photosensitive drum is amorphous silicon.
