ABSTRACT:
A developing device containing an initial developer in a sealed initial developer storage space sealed with a film and a magnetic toner in a sealed toner container is mounted on the frame of an electrostatic apparatus. Then, the film sealing the initial developer storage space and the toner container is removed to let the initial developer fall into an initial developer containing space near a developing sleeve and to let the magnetic toner fall into a space separated from the initial developer containing space by a partition wall. As the magnetic toner of the initial developer is consumed with the progress of printing operation, the toner flows through a gap defined by the partition wall into the initial developer containing space. The initial developer and the magnetic toner can be surely supplied to the developing sleeve simply by removing the film before using the developing device.
