Topic
When installing the developing unit in the machine while shifting it rightwards, in a very rare case, the developer
lock at the machine side might not be able to be released if the notch at the bottom of the developer case is hooked,
and detachment of the developing unit might be hard. Therefore, the shape of the bottom of the developer case was
changed.
