摘要： In an image forming apparatus, a lubricant is fed to an image carrier on which a toner image is to be formed. An endless rotatable transfer member conveys a recording medium to which the toner image is to be transferred from the image carrier. The transfer member is capable of contacting the surface of the image carrier to which the lubricant has been applied. As a result, an adequate amount of lubricant is evenly applied to the transfer member to reduce the coefficient of friction of the surface of the transfer member, thereby enhancing the cleanability of the transfer member.

摘要： A transfer separator comprises a transfer belt or other transfer mechanism for carrying and conveying a sheet to apply a toner image from an image carrier onto the sheet and separating the sheet from the image carrier. A bias application electrode applies a transfer bias to the transfer belt, wherein a relation of Lp.gtoreq.aV, and a=1 mm/KV is established when the minimum distance between the image carrier and surface of the bias application electrode is set to Lp (mm) and the maximum voltage applied to the bias application electrode is set to V (KV) . Preferably, the bias application electrode has a coated layer, and the difference in thickness resistance between the coated layer and the transfer belt is within two orders of magnitude. The hardness of the coated layer is preferably equal to or greater than the hardness of the transfer belt.
