Abstract
In a developing device for electrostatic recording using a liquid developer, a first connector member firmly receives one end of a developer supply pipe and one end of a developer retrieval pipe, and a second connector member is firmly fitted in an opening of a developer storage tank for closing the same and firmly receives one end of pipes which open at opposite end to the inside of the developer storage tank. The developer storage tank is movable in a direction to fit the first and second connector members closely together under pressure for interconnecting the pipes retained by the first connector member and the corresponding pipes retained by the second connector member. With this construction, the developer storage tank can be replaced with utmost ease.
