Abstract
A developing device for developing a latent static-electric image into a visible image from developer. Various members for preventing toner leaks are attached to the developing case. A lower-edge leak prevention member is attached below the developer bearing body. End leak prevention members are attached on either side of the lower-edge leak prevention member, near lengthwise ends of a developer bearing body. Portions of the developing case where the end leak prevention members are attached, are indented lower than the portion where the lower-edge leak prevention member is attached. Resilient foam members are attached on the same surface as the lower-edge leak prevention member, with one side surface in contact with one side surface of the corresponding end leak prevention member.
