Abstract
An electrophotographic printer such as a laser printer uses a liquid toner solution in order to deliver toner having a small toner particle size. In order to maintain homogeneity of the liquid toner solution, an in-line mixer is used in the supply to an immersion bath for the developer roller. In order to further enhance mixing, return fluid from the developer roller is scraped from the developer roller with a scraper blade. The return fluid is reintroduced into the fluid supply stream through a nozzle arrangement which controls flow to the an immersion bath for the roller.
