PROBLEM TO BE SOLVED: To obtain a good image where developer is not stuck to a developing roll or a layer restricting means even when non-magnetic one component developing device is utilized in a high speed printer. SOLUTION: In the device, the developing roll 32 feeding developer to a photosensitive body belt by rotating, a layer restricting blade 38 restricting the thickness of the layer of the developer fed to the developing roll 32, a thermistor 39 detecting the temperature of the developing roll 32 or the layer restricting blade 38 and a control part controlling the rotation of the developing roll 32 according to the temperature detected by the thermistor 39 are provided. |
