    摘要： A developing device suitable for use in an electrophotographic recording apparatus includes either a toner stirring portion arranged in a toner hopper portion, the toner stirring portion being provided with a portion for varying toner conveying speed, or in the toner a toner stirring and moving means provided in a toner cartridge. A printing irregularity does not occur on a printing paper even if the printing is performed at the state where the amount of toner, which is collected in the toner hopper portion, is too reduced to sufficiently cover the toner hopper stirring portion.

    摘要： A toner residual amount detecting mechanism comprises a stirring device and a photosensor. The photosensor has a protrusion, and rotates together with a stirring shaft while the protrusion contacts with a pin planted on the stirring shaft. The stirring device rotates by its gravity when it reaches a top dead point thereof. The stirring device also includes a magnetic rotor attracted by a permanent magnet in a sensor lever to thereby turn the sensor lever about the fulcrum of the sensor lever to a predetermined position. The sensor lever is stopped by a stopper when the stirring device reaches the bottom dead point thereof. The photosensor cannot detect light when the sensor lever is positioned at the bottom dead point since the light is intercepted by the sensor lever but can detect the light when the sensor lever reaches the predetermined position. The mechanism can inform an operator of a toner supply time since the photosensor operates depending on the resistance of toner against the stirring device.

    摘要： A detachable toner cartridge for use in an electrophotographic printer includes an outer cylinder and an inner cylinder contacting each other and having respective toner discharge outlets that can be overlapped with each other by turning the inner cylinder relative to the outer cylinder so as to discharge toner. The inner cylinder is pressed against the outer cylinder in the circumferential direction to bring the cylinders into close contact to prevent toner leakage. The toner cartridge does not require so high accuracy in manufacturing thereof.

    摘要： A color image forming apparatus includes a carrier belt which runs along a transport path of a recording medium to transport the recording medium. A number of image-forming sections are aligned in the transport path. Each of the plurality of image-forming sections forms a toner image of a corresponding color included in an image signal. A plurality of transfer units are provided, with each being disposed to oppose a corresponding one of the number of image-forming sections. Each of the number of transfer units transferring the toner image of the corresponding color to the recording medium. A fixing unit is provided that fixes the toner image to the recording medium. A controller is provided that detects a number of colors in the image signal. The controller sets one set of speeds from a plurality of different sets of speeds in accordance with the number of colors. Each set of speeds includes a speed of the carrier belt, a speed at which each of the image-forming sections forms a respective toner image of a corresponding color, and a speed of the fixing unit. The speed of the carrier belt, the speed at which each of the image-forming sections forms a respective toner image of a corresponding color, and the speed of the fixing unit of any one respective set of speeds are substantially equal to each other.
