けたことを特徴とする現像装置。A developing roller is constructed of a cylindrical sleeve made of a non-magnetic material with a rotatable magnetic roller installed inside it, and the sleeve and magnetic roller are rotated relative to each other to produce a magnetic one-component developer. In a developing device that is held on a sleeve and conveyed to a developing area facing a photoreceptor on which an electrostatic latent image is formed, a doctor is provided with an opening window for toner passage that regulates the amount of the developer held on the sleeve. A developing device characterized in that one member is made of a magnetic material and is provided facing the developing roller.
