B. Toner hopper
• The toner replenishing port of the toner hopper of each color of toner is provided with a
toner spillage prevention shutter that prevents toner from spilling during removal or rein-
stallation of the developing unit.
• Mounting the developing unit pushes the shutter at the toner replenishing port, opening
the toner replenishing port. Removing the developing unit, on the other hand, closes the
shutter and toner is thereby prevented from spilling from the toner replenishing port.

NOTE
• The toner replenishing port of the developing unit is not provided with a shutter
mechanism. When removing the developing unit, the developing unit must be held
in a horizontal position with care not to allow toner to spill from the toner replen-
ishing port.
