摘要： An image forming apparatus includes an image carrier, a charging device configured to uniformly charge a surface of the image carrier with a charging member applied with a bias of a first polarity (e.g. a negative polarity) for charging. A latent image forming device forms a latent image on the surface of the image carrier uniformly charged. A developing device develops a latent image by depositing toner grains of the first polarity on the latent image to thereby form a corresponding toner image. A transferring device forms an electric field between the image carrier and a moving member that serves as a movable contact with the image carrier to thereby transfer the toner image from the surface of the image carrier to the moving member or to a recording member nipped between the image carrier and the moving member. A polarity controlling device sets residual toner to a second polarity (e.g. a positive polarity) opposite to the first polarity, before the residual toner left on the image carrier by the transferring device is conveyed to a corresponding position to the charging member.
摘要翻译：图像形成装置包括图像载体，充电装置，被配置为用施加有用于充电的第一极性（例如负极性）的偏置的充电部件对图像载体的表面进行均匀充电。潜像形成装置在均匀充电的图像载体的表面上形成潜像。显影装置通过在潜像上沉积第一极性的调色剂颗粒来形成潜像，从而形成相应的调色剂图像。传送装置在图像载体和用作与图像载体的可动触点的移动部件之间形成电场，从而将调色剂图像从图像载体的表面转移到移动部件或夹在图像载体和移动构件。在通过转印装置留在图像载体上的剩余调色剂被传送到与充电部件相对应的位置之前，极性控制装置将残留调色剂设置为与第一极性相反的第二极性（例如正极性）。
