A marking method and marking device for providing an image upon a steel material or other hardened surface. A toner image is formed on the surface of the marking drum having an elastic surface. The drum is placed in abutment with the material to be marked under pressure while at least one of the drum material to be marked is moved along the surface of the other to thereby transfer the toner image onto the surface to be marked. Toner fixing liquid is subsequently dispensed over the transferred image. Apparatus for driving and supporting the marking drum is disclosed including a swinging support arm which may be extendible in some embodiments so as to make the device capable of marking many types of surfaces.
