<P>PROBLEM TO BE SOLVED: To provide a cleaning device and an image forming apparatus capable of favorably removing an untransferred toner by smoothly changing voltages at a brush top. <P>SOLUTION: The cleaning device includes: a first cleaning brush member, which removes a normally-charged toner on a cleaning object; first voltage application means for applying voltage in the reverse polarity to the first cleaning brush member; a second cleaning brush member, which is disposed downstream the first cleaning brush member and removes a reversely-charged toner on the cleaning object; second voltage application means for applying voltage in the normal charge polarity to the second cleaning brush member; a third cleaning brush member, which is disposed downstream the second cleaning brush member and removes a normally-charged toner on the cleaning object; and third voltage application means for applying voltage in the reverse polarity to the third cleaning brush member. A brush resistance of the first cleaning brush member is lower than a brush resistance of the second cleaning brush member and of the third cleaning brush member. <P>COPYRIGHT: (C)2013,JPO&INPIT |
