像装置。 At least two developing cases are provided around the photoreceptor, and a developing roller consisting of a developing sleeve and a magnet is provided in each of the developing cases,
An image forming apparatus, wherein the developing case is provided to be swingable around an axis parallel to the rotation center of the photoreceptor, and a driving means is provided for switching the developing case between a state in which it approaches a photosensitive surface of the photoreceptor and a state in which it moves away from the photosensitive surface of the photoreceptor. In the developing device, when the developing case is alternatively switched to a state close to the photosensitive surface of the photoconductor, the developing sleeve comes into contact with a sleeve shaft of a developing sleeve provided in the developing case. A bias voltage is applied to the developing sleeve, and when the photosensitive surface and the developing sleeve are separated, a connecting terminal is made of an elastic member for releasing contact with the sleeve shaft and canceling the application of the bias voltage. Developing device for equipment.
