Claims

[Scope of utility model registration request]

An opening in a developing case in which a plurality of developing rollers that are rotatable around an axis and which contain a plurality of magnets in a non-rotating state face the outer circumferential surface of a drum-shaped photoreceptor, and in which these developing rollers house developer. In the developing device, the developing device includes a separator member disposed in the developing case and located on the opposite side of the photoconductor with the developing roller sandwiched therebetween. A developing device characterized in that a magnetic member is attached at a position approximately equal distance from the developing roller.
