ABSTRACT:
A charge roller wiper for photoconductor unit for forming a toner image in an image forming device. The photoconductor unit comprises a photoconductor drum, a charge roller and a first charge roller wiper. The photoconductor drum receives toner particles for forming the toner image that is transferred onto a media sheet. The charge roller charges the photoconductor drum. A first charge roller wiper is disposed substantially parallel to path along which the charge roller moves between a working position and a storage position. The first charge roller wiper is configured to peripherally contact and clean the charge roller when the charge roller assumes a working position. A second charge roller wiper may be provided adjacent the storage position and disposed substantially perpendicular to the first charge roller wiper and directly in the path along which the charge roller moves.
