Abstract
A recording apparatus of the present invention includes a bearing member for bearing a recording medium having toner and carrier and a backing electrode opposing to the bearing member for electrically attracting the toner on the bearing member. The toner and carrier are charged to opposite polarities. A substrate having a plurality of apertures is provided between the bearing member and the backing electrode. This allows the toner to propel from the bearing member toward the backing electrode. Further, both the toner and carrier have respective volume mean diameters smaller than a diameter of the apertures, and the volume mean diameter of the toner is larger than that of the toner. With the arrangement, the toner will propel through each aperture to form a corresponding image portion, i.e., dot, thereby forming a high quality image without any dot-defect.
