摘要:
The present invention provides a charging roller having a stable chargeability and capable of preventing occurrence of “fogging” on an electrophotographic image. The invention relates to a contact-charging type charging roller which includes a conductive support and a surface layer. The surface layer contains a binder, resin particles containing a carbon black dispersed in the binder, and graphitized particles dispersed in the binder; and the surface layer has, on its surface, convex portions derived from the resin particles, and convex portions derived from the graphitized particles. These convex portions have a specific relationship.
摘要(中):
本发明提供一种具有稳定的带电性并能够防止在电子照相图像上发生“起雾”的充电辊。 本发明涉及一种接触充电型充电辊,其包括导电支撑件和表面层。 表面层含有粘合剂,分散在粘合剂中的含有炭黑的树脂颗粒和分散在粘合剂中的石墨化颗粒; 并且表面层在其表面上具有衍生自树脂颗粒的凸部和源自石墨化颗粒的凸部。 这些凸部具有特定关系。
