登録請求の範囲第１項に記載の現像装置。[Claims for Utility Model Registration] (1) Electrostatic latent images formed in image areas alternately provided with non-image areas on the surface of a rotating latent image carrier, facing the latent image carrier in a developing area. In a developing device of an electrostatic recording device that performs development using a developer conveyed to a developing area by rotating a developing roller provided as a developing roller, when the image area comes to the developing area;
A developing device characterized in that the linear velocity of the peripheral surface of the developing roller is changed when the non-image area arrives so that the latter is smaller than the former. (2) Claims for registration of a utility model characterized in that the linear velocity of the circumferential surface of the developing roller when the non-image area comes to the developing area is approximately equal to the linear velocity of the circumferential surface of the latent image carrier. Developing device according to item 1.
