Abstract:
1. A developing apparatus comprising: a photoconductor; a photoconductor frame part to support the photoconductor; a developing roller to develop a latent image formed on the photoconductor by supplying a developer; a developing roller frame part to support the developing roller, the developing roller frame part including a developer storing part to store the developer and provided with a supplying opening through which the developer is supplied to the developing roller, wherein the developing roller frame part is rotatably coupled to the photoconductor frame part via a hinge part, the developing roller frame part including a developing roller opening through which a portion of the developing roller is exposed to the photoconductor; a leakage preventer removably attached to and sealing the supplying opening; an insertion opening defined by a portion of the photoconductor frame part and a portion of the developing roller frame part; a frame insertion member removably inserted in the insertion opening to maintain the photoconductor and the developing roller in a non-operational separated state before installation in an image forming apparatus, the insertion opening decreases in size from a larger size, when the frame insertion member is inserted in the insertion opening, to a smaller size, when the frame insertion member is removed from the insertion opening; and a connecting part to connect the frame insertion member with the leakage preventer, wherein the insertion opening is located nonadjacent to the developing roller opening of the developing roller frame part.
