置。[Claims for Utility Model Registration] A developing roller that supplies a magnetic one-component toner to an electrostatic latent image formed on the surface of a photoconductor, and a magnetic one-component toner that is provided below the developing roller and is attached onto the developing roller. A developing device having a doctor blade that regulates the layer thickness of the toner, comprising a guide plate that guides the toner upstream of the doctor blade with respect to the rotational direction of the developing roller,
A developing device characterized in that a gap between the guide plate and the developing roller is formed such that it becomes smaller from the upstream side to the downstream side with respect to the rotating direction of the developing roller.
