摘要： In an image forming apparatus of the type sequentially executing charging, exposure, development and image transfer, a device for applying a lubricant to the surface of an image carrier includes a lubricant applying member rotatable in contact with the image carrier for applying, at a position where the lubricant applying member contacts the image carrier, the lubricant to the surface of the image carrier while deforming its contour in accordance with a bite of the surface of the image carrier. A lubricant feeding unit feeds the lubricant to the lubricant applying member and includes a lubricant providing unit having a preselected thickness t. The surface of the image carrier bites into the lubricant applying member by an amount T while the lubricant providing unit bites into the lubricant applying member by an amount t' smaller than the amount T, but substantially equal to or slightly greater than the thickness t. The device has a low cost, compact configuration and can use up the lubricant without any waste while desirably applying it to the image carrier.

摘要： An image forming apparatus capable of adequately adjusting the amount of a low friction agent to be applied to the surface of a photoconductive element in accordance with image quality is disclosed. After preselected initialization, an electrophotographic image forming section records a usual image or a particular image for evaluation on a paper. A toner image formed on the photoconductive element and a toner image transferred from the element to a paper are read. Image data representative of such toner images and the initial image data are compared to see if the read images are defective or not. The low friction agent is applied to the photoconductive element in an amount controlled on the basis of the result of the decision.
