置の駆動装置。 a latent image carrier that forms an electrostatic latent image on its circumferential surface; a developer carrying member that develops the electrostatic latent image with a developer carried on its circumferential surface; a first rotating member that rotates together with the carrier and has an elastic circumferential surface; a second rotating member that is provided on the developer carrying member and rotates together with the developer carrying member and has an elastic circumferential surface; By bringing the elastic circumferential surfaces of the second rotating member into pressure contact with each other, the rotational driving force is transmitted from one rotating member to the other rotating member using a frictional force between both elastic circumferential surfaces. 1. A drive device for an image forming apparatus, comprising a pressure means.
