Patent ID: 8433213

Claim:
A cleaning device comprising: a normally charged toner cleaning unit including a normally charged toner cleaning member that is applied with a voltage having a reversed polarity relative to a normally charged polarity of a toner and electrostatically removes the toner having the normally charged polarity on a body to be cleaned, a normally charged toner recovery member that makes the toner on the normally charged toner cleaning member electrostatically move to a surface of the normally charged toner recovery member and recovers the toner, and a normally charged toner scraping member that rubs the surface of the normally charged toner recovery member and scrapes off the toner on the normally charged toner recovery member; a reversely charged toner cleaning unit including a reversely charged toner cleaning member that makes contact with the body to be cleaned while rotating, is applied with a voltage having a polarity same as the normally charged polarity of the toner, and electrostatically removes the toner having a reversed polarity relative to the normally charged polarity on the body to be cleaned, a reversely charged toner recovery member that makes the toner on the reversely charged toner cleaning member electrostatically move to a surface of the reversely charged toner recovery member and recovers the toner, and a reversely charged toner scraping member that rubs the surface of the reversely charged toner recovery member and scrapes off the toner on the reversely charged toner recovery member; and a pre-cleaning unit including a pre-cleaning member that is arranged upstream of the normally charged toner cleaning member and the reversely charged toner cleaning member in a movement direction of a surface of the body to be cleaned, makes contact with the body to be cleaned while rotating, is applied with a voltage having a reversed polarity relative to the normally charged polarity of the toner, and electrostatically removes the toner having the normally charged polarity, a pre-recovery member that makes the toner on the pre-cleaning member electrostatically move to a surface of the pre-recovery member and recovers the toner, and a pre-scraping member that rubs the surface of the pre-recovery member and scrapes off the toner on the pre-recovery member, wherein a toner recovery ability of the normally charged toner scraping member from the normally charged toner recovery member and a toner recovery ability of the reversely charged toner scraping member from the reversely charged toner recovery member are set to be smaller than a toner recovery ability of the pre-scraping member from the pre-recovery member.
