To stabilize the supply of color material particles as well as reduce the wasteful amount of color material particles used and suppress deformation or damages of the outer walls of a plurality of cell regions partitioned by partition walls provided upright, an interval holding section having a first height dimension for holding an interval between a non-display area of the surface of a substrate for a display panel, which has an electrode at each of the cell regions, and a non-transfer area of the surface of an electrophotographic transfer body, is provided between the non-display area of the surface of the substrate and the non-transfer area of the surface of the transfer body, at a predetermined value at the time when the transfer body transfers the color material particles to the substrate, and the color material particles are transferred to the substrate from the transfer body while biasing the substrate toward the transfer body in such a way that the interval holding section holds the interval between the non-transfer area of the transfer body and the non-display area of the substrate at the first height dimension.
