摘要：
A developing device includes a developer bearer to carry developer to a developer range where the developer bearer faces a latent image bearer, a development casing forming a developer storing part storing the developer to supply to the surface of developer bearer, a developer through opening communicating a space in where the developer bearer is disposed and the developer storing part, a cover sheet covering the developer through opening at the developing casing, and when the cover sheet is removed, the developer pass through the developer through opening, a sheet collecting shaft to collect the cover sheet by rotating, and a transmitting mechanism to transmit a force for rotating to the sheet collecting shaft. The transmitting mechanism does not transmit the force to the collecting shaft after the cover sheet is collected.
