Abstract:
1. An image forming apparatus comprising: an image bearing member bearing a toner image; a transfer unit, which electrostatically transfers the toner image on the image bearing member to a recording material; a first cleaning member to which a voltage having a predetermined polarity is applied to remove toner on the image bearing member; a second cleaning member to which a voltage having a polarity opposite to the predetermined polarity is applied to remove toner from an area of the image bearing member from which the first cleaning member has removed the toner; an input unit in which information on a type of the recording material is inputted; and a voltage changing unit, which changes voltages applied to the first and second cleaning members based on the information on the type of the recording material inputted in the input unit, wherein the voltage changing unit increases absolute values of the voltages applied to the first and second cleaning members as a smoothness of the recording material is decreased.
