An image forming apparatus includes an image carrying member which carries an image composed of a developer, a lubricant application device which applies a lubricant onto the image carrying member, and a cleaning blade which abuts against the image carrying member to scrape the developer. The cleaning blade is formed of a material whose tensile stress-elongation test shows that the definite integral of a tensile stress with respect to an elongation percentage on an interval between the elongation percentage of zero and the elongation percentage at which the stress is a predetermined value is a predetermined upper limit value or less.

Disclosed is an image forming method including forming a concave-convex pattern on a surface of a plate by pressing the plate and a mold having the convex-concave pattern on a surface thereof against each other, the plate having the surface made of a material in which a hardness changes reversibly at a transition point temperature, forming a plate image constituted of a concave-convex region having the concave-convex pattern and a smooth region in which the concave-convex pattern is erased on the plate by erasing the concave-convex pattern by selectively heating the surface of the plate to the transfer point temperature or above corresponding to an image signal, and forming an image on a recording medium by forming an ink image on the plate by applying an ink on the plate image and by transferring the ink image on to the recording medium.
