Abstract

PURPOSE:To prevent a developer layer which is formed when a nondevelopment state continues from being packed by providing a means which releases press contacting in the nondevelopment state. CONSTITUTION:The gap of a development area constituted by the developing sleeve 22 and image carrier 11 of the developing device 20 is adjusted automatically in developing operation and expanded exceeding its adjustment range when the developing operation is stopped. Therefore, a developer can be rubbed against the image carrier with stable rubbing force. Consequently, even when the device is not in operation, the developer is prevented from being packed and an image of invariably superior quality can be developed.
