摘要:
A content server (10) includes a receiving unit (14) that receives a request signal from a request source terminal, an acquisition unit (15) that acquires an IP address assigned to the request source terminal from the request signal, and a determination unit (16) that determines a location region of a user of the request source terminal by referring to an address storage unit (11) based on the acquired IP address. The address storage unit (11) stores address information including location regions of registered users set based on addresses of the registered users and IP addresses assigned to terminals of the registered users in association with each other.
摘要:
A charging member, which is to be provided in contact with an object member and to which a voltage is to be applied to electrostatically charge the object member, has a substrate, and a metal layer and a surface layer of a seamless tube. The charging member may be used with a process cartridge and an electrophotographic apparatus.
摘要:
A contact charging member to be abutted against a charge-receiving member and supplied with a voltage for charging the charge-receiving member is provided. The charging member includes an electroconductive substrate, an elastic layer and a surface layer disposed in lamination. The surface layer comprises crosslinked polymer crosslinked by irradiation with an electron beam. The surface layer may preferably be in the form of a seamless tube formed of the crosslinked polymer. The surface layer crosslinked by electron beam irradiation is less liable to suffer from transfer of a crosslinking agent or a decomposition product thereof to the charge-receiving member. Accordingly, the charging member shows improved durability and stably uniform charging ability suitable for electrophotographic image formation under various environmental conditions.
摘要:
A light-resistant polyaniline light-shielding film, comprising a thin polyaniline film in which Lewis acid is contained in an amount of 0.1 to 5 mol % per monomer unit of the polyaniline. The thin film is used as a black matrix for a liquid crystal display device. The device thus obtained has high reliability.
