摘要： The present invention provides a development apparatus which can operate free from development ghost or bias leak, can form a good image free of defects such as development ghost even if the foregoing negative-working magnetic one-component developer is used and can exhibit an excellent environmental stability of image density even under high temperature and humidity conditions. The magnetic one-component development apparatus according to the present invention comprises a developer carrier provided opposed to an electrostatic latent image retainer. The surface the developer carrier comprises an electrically-conductive resin layer containing as a particulate electrically-conductive material a carbon black and a graphite. The ash content in the graphite is not more than 3.0% by weight. The volume intrinsic resistivity of the electrically-conductive resin layer preferably falls within a range of from 2.0.times.10.sup.-2 to 0.99 .OMEGA..multidot.cm. As the developer to be supported on the developer carrier there may be used a negatively-chargeable magnetic one-component developer.
摘要翻译：本发明提供一种能够免受显影重影或偏置泄漏操作的显影装置，即使使用上述负性磁性单组分显影剂，也可以形成没有诸如显影重影的缺陷的良好图像，并且可以显示出优异的环境图像浓度即使在高温和高湿条件下也能保持稳定。根据本发明的磁性单组分显影装置包括与静电潜像保持器相对设置的显影剂载体。显影剂载体的表面包括导电树脂层，其包含作为颗粒状导电材料的炭黑和石墨。石墨中的灰分含量不超过3.0重量％。导电性树脂层的体积固有电阻率优选在2.0×10 -2〜0.99欧姆×xcm的范围内。作为显影剂载体上支持的显影剂，可以使用带负电荷的磁性单组分显影剂。
