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, wherein the developing roller frame part is rotatably coupled to the photoconductor frame part via a hinge part; a developer storing part to store the developer and provided with a supplying opening through which the developer is supplied to the developing roller; 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 spacer removably inserted in the insertion opening to maintain the photoconductor and the developing roller in a non-operational separated state; and a connection part to connect the spacer with the leakage preventer, wherein the spacer is configured to contact with the portion of the photoconductor frame part and the portion of the developing roller frame part which define the insertion opening in the non-operational separated state.
