ABSTRACT:
A developing device includes a developer bearing member and a shock absorbing member. The developer bearing member includes a developing region across from an image bearing member including an image forming region, and a center portion including an image creating region corresponding to the image forming region on the image bearing member. The developer bearing member is configured to bear the developer on the surface thereof and transport the developer to the developing region while moving the surface. The shock absorbing member is provided to each of both ends of the developer bearing member in a width direction thereof across from the image bearing member. Each of both ends of the developer bearing member is provided outside the center portion of the developer bearing member, and an outer diameter of each of both ends of the developer bearing member is substantially smaller than an outer diameter of the center portion.
