A developing apparatus develops a latent image with a liquid developer includes a developer container capable of containing the liquid developer therein, a developer carrying device that carries the developer thereon and develops a latent image thereon, a developer applying device that applies the developer to the developer carrying device and forms a thin developer layer thereon, and a developer supplying device positioned in contact with the developer applying device and supplies the developer from the developer container to the developer applying device. The developer-supplying device is separated after the developer carrying device develops a latent image, while the developer applying device removes the developer remaining on the developer carrying device.
