摘要： An apparatus and method for detecting an empty condition of toner cartridges containing toner for copiers, fax machines, printers and the like is disclosed. The cartridges may be mounted to a rotary developing device. According to one embodiment, when a toner cartridge has been rotatably positioned to a developing position, an empty condition is detected by emitting light into the toner cartridge and detecting the light coming out of its bottom. To accomplish this detection, a light source and a light sensor are fixedly located near a bottom corner of the toner cartridge at the developing position. Light is emitted into the toner cartridge at a predetermined oblique angle with respect to a side wall of the toner cartridge. Light exits out from the bottom wall if a predetermined amount of toner does not exist in the toner cartridge. Due to the oblique angle, the distance between the light source and the light sensor is substantially reduced and provides an accurate measurement. This reduced distance also results in a smaller end detection system.

摘要： A color image forming apparatus capable of superposing toner images of respective colors in accurate register by preventing an exposing position from being displaced in the subscanning direction. The rotation phase of a polygonal mirror is controlled on the basis of the mark detection timing of a mark sensor. Hence, the exposing position in the subscanning direction is prevented from being displaced without regard to irregularities in the circumferential length and feed speed of an intermediate image transfer belt.

摘要： In a color image forming apparatus, a plurality of color images of component colors are combined to form a full color image. These images of the component colors are overlapped on an intermediate recording medium, and are then transferred to a transfer medium. Control circuitry reduces the amount of time required to form the component color images on the intermediate transfer medium, and to prevent an abnormality such as an out-of-phase or pull-out of a closed loop control circuit for controlling such a formation of the component color images. This may be achieved by abruptly changing a phase of a motor synchronizing signal. Further, for a period of time after the motor synchronizing signal is abruptly changed, a gain of an amplifier in the motor control circuit can be reduced, an abnormality detection in the motor control circuit can be reduced, the motor control circuit can be placed in an open loop state, or an addition or subtraction signal can be input to the closed loop motor control circuit. This specified period can also be detected based on a feedback including a rotational phase of a polygon motor formed as part of a unit for writing the individual component color image signals.
摘要翻译：在彩色图像形成装置中，组合颜色的多个彩色图像被组合以形成全色图像。这些分量颜色的图像重叠在中间记录介质上，然后被转印到转印介质上。控制电路减少在中间转印介质上形成分量彩色图像所需的时间量，并且防止诸如闭环控制电路的异相或拉出之类的异常以控制这种形成分量彩色图像。这可以通过突然改变电动机同步信号的相位来实现。此外，在马达同步信号突然变化之后的一段时间内，可以减小马达控制电路中的放大器的增益，可以减少马达控制电路中的异常检测，马达控制电路可以放置在开环状态或加法或减法信号可以输入到闭环电动机控制电路。也可以基于包括形成为用于写入各个分量彩色图像信号的单元的一部分的多边形电动机的旋转相位的反馈来检测该指定时间。

摘要： An image forming apparatus which automatically adjusts an image density when at least one of conditions of an optical writing operation, including a size of a dot image, a light strength of a laser beam, a mode of image resolution, and a scanning speed of the laser beam, is changed. When an instruction by an operator for changing the conditions of the optical writing operation is input, an optical writing controller executes a change of the conditions and a process controller then executes an operation of determining a development potential and associated bias potentials on the basis of the changed conditions of the optical writing operation. In the operation of determining a development potential and associated bias potentials, a predetermined reference dot image is written on a photoconductor by a laser beam under the changed condition of the optical writing operation and is developed with color toner under the determined development potential and associated bias potentials. The created reference dot image is then measured by a photosensor to calculate a degree of image density. On the basis of the measurement of the image density, the determined development potential and associated bias potentials are corrected to be appropriate.
