In an electrophotographic apparatus that transmits the driving force of a drive motor to the developing roller and rotates the developing roller while pressing it against a photoreceptor to visualize a latent image on the photoreceptor, the drive gear includes a gear. A cylindrical part is formed coaxially with the part, and the drive gear is supported so as to be slidable in the axial direction on the support shaft, and the cylindrical part is fitted without loosening into a photoreceptor support frame that supports the photoreceptor. , a positioning hole is formed for positioning the photoreceptor support frame, the driving gear is biased in a direction in which the cylindrical portion is fitted into the positioning hole, and the developing roller is bent when the driving gear is connected to the positioning hole. An electrophotographic apparatus, further comprising a biasing member that slides the drive gear in an axial direction to remove the cylindrical portion from the positioning hole.
