    摘要： Image forming equipment having a developing device for developing a latent image electrostatically formed on an image carrier by a developer, and a cleaning device for removing the developer remaining on the image carrier and collecting it in a collecting section. The equipment determines whether or not the developer collected in the collecting section has reached a predetermined amount by determining whether or not a developer has been supplemented to the developing device a predetermined number of times. The number of times that a developer is supplemented to the developing device is counted on the basis of the output of a supplement detector which determines whether or not a developer has been supplemented. The supplement detector determines that developer has been supplied only when a predetermined number of copies have been made after a toner low/empty signal is indicated or the toner concentration is detected to increase after the toner low/empty signal is indicated.

    摘要翻译： 具有显影装置的图像形成装置，其用于显影剂静电地形成在图像载体上的潜像，以及清洁装置，用于去除残留在图像载体上的显影剂并将其收集在收集部分中。 设备通过确定显影剂是否已经对显影装置补充预定次数来确定收集在收集部分中的显影剂是否达到预定量。 根据补充检测器的输出来计算开发者补充到开发设备的次数，该补充检测器确定是否已经补充了开发者。 补充检测器确定仅在指示调色剂低/空信号之后已经进行了预定数量的复印或者在指示调色剂低/空信号之后检测到调色剂浓度增加时才提供显影剂。

    摘要： A developing device for an image forming apparatus includes a developer carrier such as a developing sleeve having a magnetic field generating device therein which carries and conveys a developer containing toner and magnetic carrier particles. The developing device also includes a first regulating member such as a blade which regulates the developer being carried and conveyed by the developer carrier, and a developer storing section stores developer scraped off the developer carrier by the first regulating member. The developer storing section includes a second regulating member arranged upstream of the first regulating member with respect to a direction in which the developer carrier conveys the developer. The developing device further includes a toner storing section provided adjacent to the developer storing section to supply toner to the developer carrier. A contact condition of the developer carried on the developer carrier with the toner supplied to the developer carrier from the toner storing section is varied in accordance with variation of a toner density in the developer carried on the developer carrier to thereby vary a condition of the developer on the developer carrier to attract the toner. The second regulating member is spaced from the developer carrier such that when a thickness of a layer of the developer on the developer carrier increases due to an increase of the toner density in the developer on the developer carrier, the second regulating member regulates an increased amount of the developer being carried and conveyed by the developer carrier. The magnetic fields, toner speeds, and distances of the regulating members to the developer carrier satisfy predetermined conditions in different embodiments.

    摘要： A two-component toner is directly supplied to a brush which is cyclically transferred while in resilient contact with a latent image carrier for developing an electrostatic latent image on the latent image carrier. After the image has been developed by the toner, residual toner is directly recovered from the brush for uniformizing the toner density on the brush.

    摘要： A charge quenching apparatus for quenching unnecessary charges on a latent electrostatic-image bearing photoconductor of an electrophotographic copying machine for making copies with clean margins when the size of the maximum-latent-image area on the photoconductor, corresponding to the size of the original, is smaller than the transfer sheet employed, in the unit magnification and in the variable magnification, and for making copies without applying excess load to a cleaning apparatus of the photoconductor when copies bearing part of the image of the original are made or when copies bearing a reduced-size image of the original are made. In the charge quenching apparatus, the size of the maximum-latent-image area selected and the size of the transfer sheet selected are compared, and charges in the area outside the area corresponding to the smaller size determined by the above-mentioned comparison are quenched.
