Development method, the hard picture formation device (10), and the picture (22) the component is explained. According to one execution form, the surface which possesses the part which the conductance which differs differs (23) the picture component which is included (22) it prepares development method, one part among those parts demarcates, picture formation pattern of the picture (56), the electric charge director where the picture particle where plural is electrified the picture component (22) over, (64) with the electric charge director where plural is electrified (62) with it gives the developer which is included, the picture component which possesses the developer the picture component (22) over, (22) approaching, gives electric field, is electrified (62) And making use of electric field, the picture component (22) the surface (23) inducing the picture particle which is electrified in one part among the parts, it includes the fact that you develop the picture.
