PROBLEM TO BE SOLVED: To provide an image forming device where an image can always be formed stably and that is superior in durability by preventing beforehand generation of various nonconformities arising with increase of deteriorated toner with lowered fluidity or static charge characteristic when the ratio of the deteriorated toner is increased within the toner due to repeated developing. SOLUTION: In this image forming device, a toner containing chamber 27 to contain toner that is non magnetic and one component, a developing cartridge 36 provided with a developing roll 22 and a layer thickness restriction blade 23 and a photoreceptor drum 21 are provided to be able to be separated and a toner empty sensor detecting toner empty in a state where the toner is remaining at least in the developing cartridge 36. |
