摘要：
An image forming apparatus includes a member to be charged for carrying an electrostatic image, a contact-charging means for charging the member to be charged in contact with the member to be charged, and a developing means for developing the electrostatic image carried on the member to be charged. The developing means includes a developer for developing the electrostatic image comprising a toner and hydrophobic inorganic fine powder. The hydrophobic inorganic fine powder not only improves the fluidity of the developer and adjusts the chargeability of the developer but also prevents difficulties due to interaction between the member to be charged and the contact charging means in the presence of residual developer, such as damages of the member to be charged and toner-sticking onto the member to be charged.
摘要（中）：
图像形成装置包括要充电以承载静电图像的构件;接触充电装置，用于对待充电构件进行充电的充电装置;以及显影装置，用于使携带在构件上的静电图像显影 待充电。 显影装置包括用于使包含调色剂和疏水性无机细粉末的静电图像显影的显影剂。 疏水性无机细粉不仅提高了显影剂的流动性，而且调节了显影剂的带电性，而且还防止了在残留显影剂存在下被充电元件与接触充电装置之间的相互作用所引起的困难，例如 被充电的构件和调色剂粘附到要充电的构件上。
