Abstract
In a developing device in which initial developer is sealed in and a developer discharge mechanism (a trickle mechanism, or an ACR mechanism) is provided, the driving-torque load generated in the developing device is suppressed, regardless of the state of distribution of the developer that is sealed in the developing device. The order of releasing seals provided over openings is defined as follows. First, a seal provided on the downstream side of a stirring chamber starts to be released. Then, a seal provided over a discharge port is released. Lastly, a seal provided on the upstream side of the stirring chamber starts to be released.
