Particulate material cleaning apparatus

摘要

A toner cleaning apparatus using particulate cleaning material includes a particulate cleaning material replacement device which receives a container of fresh cleaning material. The container is inverted by the device and material is metered onto a brush in response to normal operation of the apparatus. Old material is automatically stripped off the brush in the replacement process. New material cannot be added without removing old material, thereby preventing overloading of the brush. A movable skive stripping member is also disclosed to automatically remove old particulate material from the brush when new particulate material is added.
