のブレード加圧機構。 The toner is sucked onto the circumferential surface of the developing roller, the sucked toner is made into a thin layer by a blade that elastically presses against the circumferential surface of the developing roller with a coil spring, and the thin layer of toner is attached to the photoreceptor. In a developing device of an electrophotographic recording device that visualizes an electrostatic latent image on a photoreceptor, a developing device is provided with a mandrel inserted through the center of the coil spring, and has an opening through which the mandrel passes through. A blade pressurizing mechanism for a developing device, comprising a spring cap attached to the device main body to receive one end of the coil spring.
