| An inkjet printhead includes a compact substrate of increased stability and structural integrity to provide a high resolution 600 dot-per-inch nozzle array having a one-half inch swath. A plurality of ink vaporization chambers are respectively aligned with the nozzles in two longitudinal columns, one column extending longitudinally along one edge of the substrate and a second column extending longitudinally along an opposite edge of the substrate, with ink feed channels communicating through an ink passage from an underside of the substrate around both edges of the substrate to the vaporization chambers. The ink feed channels have thereby been eliminated from the central portion of the substrate, and replaced by the ink feed channels at the edges of the substrate. | ||||||

| An intermediate transcription drum is supported so as to be driven in contacting relationship with a photosensitive belt. The rotating speed of the photosensitive belt driving motor is controlled by a control unit such that one rotation cycle of the intermediate transcription drum becomes a given cycle. An adjustment of the speed control data for the photosensitive belt driving motor is performed in the interval between electrostatic latent image forming. Thereby, a speed difference between the photosensitive belt and the intermediate transcription drum does not occur, and a plurality of the toner images can be transferred and accurately superposed onto the outer surface of the intermediate transcription drum. | ||||||

| A thermal printing head in accordance with the present invention has a substrate formed of an electrical insulator, heating elements formed on the substrate, and conductive layers formed on the part of the heating elements that is adjacent to and on either side of heat generating portions of the heating elements. The resistivity of heating elements is set at a value of not less than 1000 .mu..OMEGA..cm and, simultaneously, the thickness of conductive layers is set at a value of not more than 300 nm. By virtue of this arrangement, it is possible to reduce the distance between the heat generating portions of the head and the printing paper or ink sheet, and the thin conductive layers contribute to minimizing diffusion of the heat. The thermal printing head is therefore capable of efficiently and accurately transferring heat generated by the heat generating portions to the printing paper or ink sheet. The head is suitable for producing half-tone prints and is capable of producing highly gradated prints such as fully-colored prints. | ||||||

| When sub-images are sequentially transferred and connected together to form a larger image than would be possible with a single transfer operation, the occurrence of a color change in the overlapping region of the sub-images is suppressed and the width of the overlapping region is reduced as much as possible. Color image data are divided into image data of two sub-images containing an overlapping region and having edges that coincide for each color ink transferred to paper. Color values of the color image data in the overlapping region are converted by using a color conversion factor group created in advance for each position on the overlapping region so as to cancel out a color change that occurs in the overlapping region when the sub-images are transferred with one overlapping the other. The image data of the sub-images are corrected by adjusting converted color values in the overlapping region by using a correction factor for print density at each position on the overlapping region. A color image is formed by sequentially transferring the sub-images in accordance with corrected image data thereof so that the sub-images overlap at the overlapping region. | ||||||
