Abstract
A developer roll includes end seal regions subject to accumulating residual toner. An adjacent photoconductive member has a longitudinal extent with a central area defining an imaging region and longitudinal ends outside the central area defining non-imaging regions. The photoconductive member has a length extending beyond a length of the developer roll so that the end seal regions of the developer roll contact the non-imaging regions of the photoconductive member. During cleaning, the non-imaging regions become charged and discharged to electrostatically attract and transfer away the toner from the end seal regions. A blade scrapes clean the toner from the photoconductive member.
