ITB cleaning stage
Step 8: ITB cleaning
The ITB cleaning roller and the cleaning brush are applied with the DC positive bias to charge the
residual toner positive. Because the primary transfer pad is also applied with the DC positive bias, the
positively charged residual toner is reverse-transferred to the photosensitive drum from the ITB surface.
