Abstract:
1. A method for manufacturing a driving device frame for an image forming apparatus including a plastic base plate, and at least one plastic supporting shaft formed integrally with the base plate to support at least one power transmission member, the method comprising: preparing an injection mold having at least one adjusting pin to form a hollow portion extending axially in the at least one supporting shaft; forming a molded product using the injection mold; inspecting the molded product, thereby detecting verticality of the at least one supporting shaft; and moving the at least one adjusting pin of the injection mold when the detected verticality of the at least one supporting shaft is outside a tolerance range, thereby adjusting the verticality of the at least one supporting shaft, wherein the detecting verticality of the at least one supporting shaft includes detecting an inclination direction of the supporting shaft with regard to a direction perpendicular to the base plate.
