摘要： A developing device using a magnetic mono-component developing agent includes a rotary sleeve that accommodates a stationary magnet, and a toner layer thickness regulating member that regulates a thickness of a toner layer formed on the rotary sleeve. The toner layer thickness regulating member includes a blade formed of a plate-like member made of a magnetic material and a magnet attached to the blade on a side upstream in a rotation direction of the rotary sleeve. The magnet is disposed in such a manner that a direction of a magnetic field generated in a portion of the magnet on a side of the rotary sleeve is almost in parallel with the rotation direction of the rotary sleeve.

摘要： An image forming apparatus for forming a color image has developing devices with different color toners. Each developing device has a toner carrier and a layer thickness-controller facing the carrier. Circularity of toner in a particular color is smaller than that of toners in other colors. The layer thickness-controllers of the developing devices containing toners in other colors contact the carrier at a particular linear pressure. Additionally, the coefficient of variance (CV value) of the particle diameter distribution of toner in a particular color may be defined by the formula CV ⁢ ⁢ VALUE = ( STANDARD ⁢ ⁢ DEVIATION ⁢ ⁢ OF ⁢ ⁢ VOLUME - AVERAGE ⁢ ⁢ PARTICLE ⁢ ⁢ DIAMETER ⁢ ⁢ DISTRIBUTION ) ( ARITHMETIC ⁢ ⁢ VOLUME ⁢ - AVERAGE ⁢ ⁢ PARTICLE ⁢ ⁢ DIAMETER ) × 100 and may exceed the CV value of the toners in other colors. The image forming apparatus contains the contaminating toner in the developing device, makes the image resistant to color mixing, and reduces image staining, even if there is leakage of a toner and contamination of the toners in different colors with the scattered toner.
摘要翻译：用于形成彩色图像的图像形成装置具有不同颜色调色剂的显影装置。每个显影装置具有面向载体的调色剂载体和层厚控制器。特定颜色的调色剂的圆形度小于其他颜色的调色剂。含有其他颜色的调色剂的显影装置的层厚度控制器以特定的线性压力接触载体。另外，特定颜色中的调色剂的粒径分布的变异系数（CV值）可以由公式CV≠VALUE =（STANDARDÉÉ⁢⁢⁢⁢⁢⁢⁢⁢⁢⁢⁢⁢⁢⁢⁢⁢⁢ 直径分配）（ARITHMETIC呃VOLUME-AVERAGE⁢PARTICLE⁢DI DITERTER）×100，并且可以超过其他颜色的调色剂的CV值。图像形成装置包含显影装置中的污染调色剂，使得图像耐混色，并且即使存在调色剂泄漏并且与散射调色剂污染不同颜色的调色剂，也可以减少图像污染。

摘要： A developing device supplies developer to an electrostatic latent image bearing body of an image forming apparatus. The developing device includes a container housing with an opening in a position opposite to the electrostatic latent image bearing body and stores developer to be supplied to the electrostatic latent image bearing body. A developing roller is rotatably disposed so that a part of the developing roller is exposed from the opening. A regulator is disposed along an axial direction of the developing roller and has a leading end facing the developing roller to regulate the thickness of developer layer on the developing roller. Two holders support the developing roller and the regulator on the container housing. Each holder includes a developing roller support for supporting an end part of the developing roller and a regulator retainer for retaining the regulator on the container housing.

摘要： An imaging apparatus includes a toner ejection mode whereby toner stored in a black developing container is completely removed from the developing container by rotating a rotary developing unit at a specific timing and using gravity and the centrifugal force that acts on the toner stored in the black developing container due to this rotation, or using the vibration that acts on the black developing container when the rotation is stopped. In this toner ejection mode, the toner is ejected from the developing container of the rotary developing unit, an image for a single sheet of recording paper is formed on the surface of a photoreceptor drum, and the toner constituting the image transferred onto the surface of an intermediate transfer belt by the photoreceptor drum is then recovered by a belt-cleaning unit.
