Image forming apparatus and process cartridge detachable thereto with charging member pressure contact release feature
摘要：
In a process cartridge detachable from an image forming apparatus, presssure contact between a charging member, and an image bearing member for bearing an image can be released. Hence, it is possible to prevent the occurrence of traces caused by pressure, creep, and contamination in the image bearing member and the charging member. In addition, by arranging so that the process cartridge cannot be mounted in the image forming apparatus in a state in which the pressure contact between the charging member and the image bearing member is released, failure in charging on the image bearing member by the charging member can be prevented.
摘要（中）：

在可从图像形成装置拆卸的处理盒中，可以释放充电构件和用于承载图像的图像承载构件之间的压力接触。 因此，可以防止在图像承载部件和充电部件中产生由压力，蠕变和污染引起的痕迹。 此外，通过这样布置，使得处理盒不能安装在图像形成装置中，在充电构件和图像承载构件之间的压力接触被释放的状态下，充电构件对图像承载构件的充电失败 可以防止。
