A developing device is provided for an image forming apparatus that has a photoreceptor. The developing device has a housing with upper and lower housing pieces that are snap fit together. A developer opening is formed in an upper portion of the upper housing piece for supplying a developer and a bottom opening is formed in a bottom part of the upper housing piece. A developer carrier and a developer agitating member are supported rotatably in the upper housing so that an axis of the developer agitating member is below an axis of the developer carrier and below the developer opening. The lower housing piece is configured to seal the bottom opening of the upper housing piece. However, the snap fit housings can be separated for cleaning as necessary.
