Abstract: The platemaking apparatus according to the present invention forms a pattern on an ink film-forming press plate that has a surface layer containing a stimulus-responsive compound whose physical property can reversibly change in response to an external stimulus. The platemaking apparatus includes: a first stimulator that applies, to a surface of the press plate, a first stimulus that changes the physical property of the surface from a first physical property to a second physical property to form the pattern, on the basis of image data; a second stimulator that applies, to the surface of the press plate, a second stimulus that changes the physical property of the surface from the second physical property to the first physical property, to erase the pattern; and a cleaning unit that removes an ink remained on the surface of the press plate.

Abstract: The present invention provides an electrophotographic image forming method using an electrophotographic photoconductor. The electrophotographic photoconductor has a protective layer. The surface of the protective layer has a projection structure. The average distance between neighboring projections among a plurality of projections R is set within the range of 100 to 250 nm. A toner including titanate compound particles attached to toner base particles is used.
