盒和图像形成装置
摘要：
本发明公开了盒和图像形成装置。图像形成装置包含：图像承载部件；带电部件，用于与图像承载部件接触而使图像承载部件带电；以及显影部件，用于与图像承载部件接触而供给显影剂。在转印之后残留在图像承载部件上的显影剂被显影部件收集。带电部件的表面的马氏硬度HMR和显影剂的表面的马氏硬度HMD满足以下关系：HMD>HMR。
摘要（英）：

An image forming apparatus includes: an image bearing member (1); a charging member (2) for electrically charging the image bearing member in contact with the image bearing member; and a developing member (31) for supplying developer in contact with the image bearing member. The developer (T) remaining on the image bearing member after transfer is collected by the developing member. A Martens hardness HMR of a surface of the charging member and a Martens hardness HMD of a surface of the developer satisfy the following relationship: HMD > HMR.
