发明名称 Image forming apparatus, image forming method, and process cartridge
摘要 <p>The present invention provides an image forming apparatus which has high durability and allows for preventing occurrence of image blur and suppressing image degradation caused by a reduction in image density near a charging unit used under a high-humidity condition and stably forming high-quality images even when repetitively used for long hours. To this end, the image forming apparatus has at least an electrophotographic photoconductor, a corona discharge type charging unit in a non contact manner, an exposing unit, a developing unit, a transfer unit, a cleaning unit and a lubricant providing unit, wherein the outermost surface layer of the electrophotographic photoconductor contains at least a filler and an amine compound having a specific structure, the lubricant providing unit has a lubricant supplying unit configured to supply a lubricant onto the electrophotographic photoconductor and a lubricant applying unit configured to apply the supplied lubricant over the electrophotographic photoconductor surface.</p>
