置の現像装置。 Circumferential seal members are pressed against the outer periphery of both ends of the developing roller facing the non-image forming area of the photoconductor to prevent toner from leaking from both ends of the developing roller, and the toner on the developing roller is made into a thin layer with a developing blade. After that, in a developing device of an electrophotographic apparatus that adheres to the photoreceptor and develops a latent image on the photoreceptor, an engaged portion into which both ends of the developing blade fit is formed in the peripheral seal member. A developing device for electrophotographic equipment.
