2.Working principle: Control the thickness of the toner layer on the magnetic roller(MR)/developing roller(DR) and assist the toner to be charged and charged.
3.Note:
The DB cannot be pressed against each other and are prone to deformation;
If the rubber powder DB is stored for too long, the rubber will become yellow and aging .
The metal powder DB should prevent extrusion and the steel sheet is deformed.
