ABSTRACT:
A lubricating device operable to lubricate a moving imaging surface subsequent to removal of residual toner by a cleaning device includes a lubricant applicator, a metering blade, and a priming agent. The lubricant applicator is located downstream of the cleaning device in a direction of movement of the imaging surface, and applies lubricant to the imaging surface. The metering blade is located downstream of the lubricant applicator in the direction of movement of the imaging surface, and spreads the applied lubricant into a thin layer by directly contacting the imaging surface. The priming agent is prepared by mixing a lubricant and a powder, and provided, prior to initial operation, on the lubricant applicator for application to the imaging surface upon startup.
