    • An image forming apparatus has an image bearing member, a charger for charging the image bearing member image forming means for selectively erasing charge on the image bearing member to thereby form an electrostatic image, and a developing device for developing the electrostatic image. The developing device includes a developing roll contacting with the image bearing member and is capable of having a developing bias applied thereto and contacting and spacing device for contacting and spacing the developing roll with respect to the image bearing member. The contacting and spacing device contacts the developing roll having the developing bias applied to the area thereof charged by the charger with the image bearing member at a start of image formation.
    • 图像形成装置具有图像承载部件,用于对图像承载部件图像形成装置进行充电的充电器,用于选择性地擦除图像承载部件上的电荷,从而形成静电图像;以及显影装置,用于使静电图像显影。 显影装置包括与图像承载部件接触并能够施加显影偏压的显影辊和用于使显影辊相对于图像承载部件接触和间隔的接触和间隔装置。 在图像形成开始时,接触和间隔装置接触显影辊,该显影辊具有施加到由充电器充电的区域的显影偏压与图像承载部件。
