    摘要： A novel titanyl phthalocyanine crystal, a photoconductive material comprising the same, and an electrophotographic photoreceptor using the same are disclosed. The titanyl phthalocyanine crystal has a primary particle diameter ranging from 0.03 to 0.15 .mu.m, shows a maximum X-ray diffraction peak at a Bragg angle (2.theta..+-.0.2.degree.) of 27.3.degree., has a ellipsoidal tabular form, and has a BET specific surface area of not less than 35 m.sup.2 /g. The crystal has improved crystal form stability against solvents and holds its crystal form for an extended period of time in a dispersed and coated state. An electrophotographic photoreceptor using the crystal as a photoconductive material is excellent in sensitivity, stability, and durability.

    摘要： An electrostatic recording head comprises an insulating substrate having a builtup structure thereon. The builtup structure includes, in the following order, a plurality of dielectric electrode strips having portions which are arranged in parallel to and kept away from one another, a first insulating layer, a plurality of discharge electrode strips each extending to intersect with the respective portions of the dielectric electrode strips, a second insulating layer having a plurality of openings to form part of an ion generating space region at individual intersected portions of said discharge electrode strips and said dielectric electrode strips, and a screen electrode which is provided to complete each ion generating space region in association with the second insulating layer and has a plurality of openings, through which ions are passed, corresponding to the respective ion generating space regions. The screen electrode is made of a member which is selected from the group consisting of metals, noble metals and alloys mainly composed of these metals and which has a melting point not lower than 1500.degree. C. Alternatively, the screen electrode may be made of a core member and a surface layer which is made of the above metal member, or an oxidation-resistant material such as an inorganic compound, a polymer or a metal alkoxide polymer.
