1. An assembling method of a cartridge detachably mountable to a main assembly of an image forming apparatus and having a developing device, said method comprising the steps of:preparing a container unit provided with a developing frame; mounting a toner-supplying roller to the developing frame, wherein the toner-supply roller is effective to supply the toner to a developing roller, and the developing roller is effective to carry the toner to a developing position; mounting a toner-layer-thickness-regulating member to the developing frame, wherein the toner-layer-thickness-regulating member is effective to regulate the thickness of a layer of the toner applied on a developing roller; supporting a first shaft portion of the developing roller at one longitudinal end thereof and a first shaft portion of the toner-supplying roller at the one longitudinal end of the developing roller by a side cover, and mounting the side cover to the container unit, after the step of mounting the toner-supplying roller and after the step of mounting the toner-layer-thickness-regulating member; and supporting a second shaft portion of the developing roller at the other longitudinal end thereof and a second shaft portion of the toner-supplying roller at the other longitudinal end of the developing roller by a bearing unit, and mounting the bearing unit to the container unit, after the step of mounting the toner-supplying roller and after the step of mounting the toner-layer-thickness-regulating member.
