摘要： The invention provides a developing device using a non-magnetic type developer for developing an electrostatic latent image formed on an image carrying roller. The device comprises a developer carrying roller resiliently which is pressed against the image carrying roller and is formed of a conductive open-cell foam rubber material so that pore openings appear on the surface thereof to entrain and carry the developer to the surface of the image carrying roller for development of the electrostatic latent image. The device also comprises a developer regulating means engaged with the developer carrying roller for regulating the thickness of the developer entrained and carried thereby. The developer is composed of a toner component (T) and a resin powder component (P), one component of which has a polarity opposite to that of an electric charge of the other component generated by triboelectrification therebetween.
The invention also provides an image formation apparatus, comprising such a developing roller and an image carrying roller for carrying an electrostatic latent image formed thereon.
摘要翻译：本发明提供一种显影装置，其使用非磁性型显影剂来显影形成在图像承载辊上的静电潜像。该装置包括弹性显影剂承载辊，该显影剂承载辊压靠在图像承载辊上并由导电的开孔泡沫橡胶材料形成，从而在其表面上出现孔开口以携带显影剂并将其携带到图像承载表面用于显影静电潜像的辊。该装置还包括一个显影剂调节装置，该显影剂调节装置与显影剂传送辊接合，用于调节由此携带和携带的显影剂的厚度。显影剂由调色剂组分（T）和树脂粉末组分（P）组成，其中一个组分的摩尔电荷极性与其它组分的摩擦电荷产生的电荷极性相反。本发明还提供一种图像形成设备，其包括这种显影辊和用于承载形成在其上的静电潜像的图像承载辊。

摘要： The invention provides a developing device using a non-magnetic type developer for developing an electrostatic latent image formed on an image carrying body. The device comprises a developer carrying roller which is resiliently pressed against the image carrying body and is formed of a conductive open-cell foam rubber material so that pore openings appear on the surface thereof to entrain and carry the developer to the surface of the image carrying body for development of the electrostatic latent image. The device also comprises a developer regulating means including a thin metal blade member pressed against the developer carrying roller for regulating the thickness of the developer entrained and carried thereby. The developer regulating means further includes a compensating means for compensating for a resilient deformation of a shaft member of the developer carrying roller which is caused when the thin metal blade member is pressed against the developer carrying roller. Thus, the thickness of the developer regulated by the developer regulating means can be made substantially uniform.

摘要： An electrostatic latent image formed on a photosensitive drum is electrostatically developed with a non-magnetic type developer, and is electrostatically transferred from the drum to a paper. The developer is composed of a toner component and a resin powder component, one component of which has a polarity opposite to that of an electric charge of the other component generated by triboelectrification therebetween. In the developing process, a conductive foam rubber developing roller (22b) is used, which includes a conductive tubular foam rubber roller element, and a metal shaft inserted into a central bore thereof. The roller element has an outer thicker portion including a conductive filler dispersed therein, and an inner solid skin layer defining the central bore thereof and exhibiting an electrical resistivity considerably higher than that of the thicker portion for lack of conductive filler. Nevertheless, a sufficient electrical contact is established between the roller element and the shaft. A thin metal blade (22c) is pressed against the roller (22b) for regulating the thickness of the developer entrained thereby, and is arranged to compensate for a resilient deformation of the shaft caused when pressing against the blade (22c) the roller (22b).

摘要： An electrostatic latent image formed on a photosensitive drum is electrostatically developed with a non-magnetic type developer, and is electrostatically transferred from the drum to a paper. The developer is composed of a toner component and a resin powder component, one component of which has a polarity opposite to that of an electric charge of the other component generated by triboelectrification therebetween. In the developing process, a conductive foam rubber developing roller (22b) is used, which includes a conductive tubular foam rubber roller element, and a metal shaft inserted into a central bore thereof. The roller element has an outer thicker portion including a conductive filler dispersed therein, and an inner solid skin layer defining the central bore thereof and exhibiting an electrical resistivity considerably higher than that of the thicker portion for lack of conductive filler. Nevertheless, a sufficient electrical contact is established between the roller element and the shaft.
A thin metal blade (22c) is pressed against the roller (22b) for regulating the thickness of the developer entrained thereby, and is arranged to compensate for a resilient deformation of the shaft caused when pressing against the blade (22c) the roller (22b).
