A separating apparatus for separating residual matter removed from an image bearing member into developer and other foreign matter comprises a first unit to which residual matter removed from the image bearing member is conveyed, a mesh member for allowing only developer to pass among the residual matter, and a second unit to which developer is conveyed through the mesh member. The first and second units are separable from each other with the mesh member intervening therebetween. The apparatus also may include a vibration applying device for applying vibration to the mesh, a convey device for conveying residual matter to the first unit, and a discharging device for discharging developer from the second unit. The apparatus further may include a first magnetic force generating device in the first unit and a second magnetic force generating device in the second unit.
