Abstract
A developing system of a liquid electrophotographic image forming device includes a developer reservoir in which a developer is stored, a development container in which the developer is supplied from the developer reservoir, a development roller rotating opposite to a photosensitive drum in the development container, and a pumping portion connected between the development container and the developer reservoir via connection pipes. The pumping portion supplies the developer to the development container from the developer reservoir or exhaust the developer from the development container and return the developer to the developer reservoir. Accordingly, the developer supplying and exhausting unit of the developing system can be simplified.
