摘要:
The driving frequency of a head is changed in conformity with temperature, and density data is converted into an optimum head driving voltage in conformity with temperature, whereby the discharge driving frequency and driving voltage of the recording head become optimum under any temperature condition, and thus recording of high quality is ensured the since irregularities caused by the temperature variation of the recording head are eliminated. The driving voltage is set by a drive control circuit that includes a plurality of limiters, one of which is chosen in accordance with ambient temperature.

An information processing system including a circuitry configured to detect first identification information used to identify a job, generate second identification information associated with the first identification information, and create a slip on which the first identification information and the second identification information are displayed.
摘要:
The present invention relates to a water-based fluorescent ink for the purpose of measurement or judgment of the fluorescence emission in a visible light region by an excitation wavelength in a predetermined ultraviolet range, containing water, a coloring material dissolved or dispersed in water, and an organic solvent, having a plurality of fluorescent groups in the coloring material structure of the coloring material, and using a water-soluble coloring material having a sulfonic acid group as the water-soluble group in the state of a free acid, capable of improving the water resistance and the light resistance, dramatically increasing the content of the fluorescent coloring material in the ink, which has conventionally been included only by a small amount in the ink due to the concentration quenching problem, obtaining preferable fluorescence emission and water resistance of the recorded image, and providing preferable adhesion resistance to the recording medium of the coloring material and reliability.
摘要:
A negatively-chargeable electrophotographic photosensitive member, has, between a cylindrical substrate and a photoconductive layer, a first lower-part layer formed of a non-single crystal material containing silicon atoms and a second lower-part layer formed of a non-single crystal material containing silicon atoms, and on its photoconductive layer has an upper-part layer formed of a non-single crystal material containing silicon atoms. The first lower-part layer is a layer containing a periodic-table Group 13 element, and the upper-part layer has a region capable of retaining electrification charges.
