Patent ID: 8483605

Claim:
A cleaning device comprising: a normally charged toner cleaning member, to which a voltage having a polarity opposite a normal charging polarity of toner is applied, provided in contact with a rotatable cleaning target at a contact position to electrostatically remove normally charged toner from the cleaning target; a reversely charged toner cleaning member, to which a voltage having the same polarity as the normal charging polarity of the toner is applied, provided in contact with the cleaning target at a contact position upstream from the normally charged toner cleaning member in a direction of rotation of the cleaning target to electrostatically remove reversely charged toner from the cleaning target; and a pre-cleaning member, to which a voltage having the polarity opposite the normal charging polarity of the toner is applied, provided in contact with the cleaning target at a contact position upstream from both the normally charged toner cleaning member and the reversely charged toner cleaning member in the direction of rotation of the cleaning target to electrostatically remove normally charged toner from the cleaning target, the contact position between the pre-cleaning member and the cleaning target in the direction of rotation of the cleaning target having a width wider than each of a width of the contact position between the normally charged toner cleaning member and the cleaning target and a width of the contact position between the reversely charged toner cleaning member and the cleaning target in the direction of rotation of the cleaning target.
