PROBLEM TO BE SOLVED: To facilitate the assembling of a photoreceptor unit and a developing device unit, and the holding of the photoreceptive unit in an image recorder provided with the photoreceptor unit and the developing device unit combinedly. SOLUTION: In a developing device unit 30 arranged on the image forming part of the image recorder, a pair of supporting plate 40 is protrudingly provided on a photoreceptor unit 60 side, a recessed groove 41 and a hook member 42 are provided on the plates 40, and the shaft 66 and a pin 63 of the unit 60 are inserted in the groove 41, so that the both units are assembled. In the case of assembling both units 30 and 60, the shaft core of the shaft 66 of photoreceptor drum 65 is positioned lower than the position of the shaft core of the shaft of a developing roller 35, so that operation for pressuring the drum 65 downward by the rotation of the roller 35 is generated; therefore, the unit 60 is prevented from floating. |
