DEFINITION

Classification: 399/128

Exposure or charging (e.g., fatigue treatment):

(under subclass 127) Subject matter wherein a photoconductive member is exposed or charged other than for image formation.

(1) Note. For example, this subject matter may include fatigue treatments used to stabilize the photoconductive member for its next application.

100, for particle or contaminant control in removal of toner from a charging member (e.g., corona wire).

115, for charging unit having a modular or displaceable structure.

153, for simultaneous charging and exposure.

168+, for charging, per se. 296, for exposure or charging a developed image prior to transfer.
