    摘要: A liquid ejection head includes nozzles, separate chambers, a common chamber, inlet portions, a filter unit, and ribs. Droplets of liquid are ejected from the nozzles. The separate chambers are communicated with the nozzles. The inlet portions are communicated with the corresponding separate chambers. Liquid is supplied from the common chamber to the separate chambers through the inlet portions. The filter unit is disposed between the inlet portions and the common chamber to filter liquid in an area across the separate chambers in a first direction in which the nozzles are arrayed. The ribs are disposed in the filter unit at intervals corresponding in size to at least two of the separate chambers in the first direction to partition the filter unit. The inlet portions are communicated in the first direction with each other in at least one portion of each of the inlet portions facing the filter unit.

    摘要: The present invention relates to photoconductors which exhibit excellent electrical properties which are not appreciably affected by environmental changes or by repeated use. Having excellent durability during repeated printing, these photoconductors can be used to obtain large quantities of high-quality output images.The photoconductor according to the invention includes a conductive substrate and a photoconductive film on the conductive substrate. The photoconductive film includes a plurality of charge generation and transport layers, wherein each layer contains a phthalocyanine compound described in the specification by chemical formula (I) as a charge generation agent and a charge transport agent dispersed or dissolved into a binder. The concentration of the charge generation agent in an upper layer is higher than in a lower layer.

    摘要: Phthalonitrile, an alkali metal or an alkali metal compound, and a hydrogen donor compound are heated in an organic solvent to synthesize a partially hydrogenated alkali metal phthalocyanine, which is then brought into contact with a dealkalizing agent to effect substitution with hydrogen of the partially hydrogenated alkali metal phthalocyanine to thereby obtain high-purity metal-free phthalocyanine. FX-type metal-free phthalocyanine as obtained according to the foregoing procedure may be used as a charge-generating substance to produce an electrophotographic photoconductor of high image quality which is highly sensitive to near infrared rays.
