Abstract
A method for controlling a distance between a photosensitive member and a developing member in an integral or separated toner cartridge. The toner cartridge is provided with an elastic member for providing an elastic force to the developing member or to the photosensitive member, so as to force the developing member to move towards the photosensitive member, or to force the photosensitive member to move towards the developing member. A production accuracy requirement of the toner cartridge is reduced by the elasticity of the elastic member. Also a device for controlling a distance between a photosensitive member and a developing member in a toner cartridge. By using the method and the device thereof, the requirement of the manufacturing accuracy of a toner cartridge can be reduced, and the negative impact of the accuracy bias caused by abrasion can be reduced, so, the product cost is saved, and the service life of the product is increased.
