PROBLEM TO BE SOLVED: To provide an image forming device constituted so that a photoreceptor and a developing roll are prevented from rubbing each other when the photoreceptor is attached and detached and a prescribed gap can be easily held between the photoreceptor and the developing roll when the photoreceptor is attached with a simple constitution. SOLUTION: This image forming device is provided with a device main body, a first unit fitted to the device main body by holding the developing roll and a second unit attachably and detachably fitted to the first unit by holding the photoreceptor. Then, the developing roll and the photoreceptor are held so that they can be mutually finely displaced from the reference gap. Besides, the image forming device is provided with a separation member such as a leaf spring or a coil spring generating such repulsion that the developing roll and the photoreceptor are mutually separated and a positioning member maintaining the reference gap between the developing roll and the photoreceptor by resisting to the repulsion. |
