摘要:
A light-emitting device according to the present invention includes: first insulators (4) arranged so as to face each other; an emitter (2) arranged between the first insulators; a second insulator (5) functioning as a base for the first insulators and the emitter; an electrode (6) arranged to face, or contact with, the first insulators partially; another electrode (10) contacting with the second insulator and interposing the second insulator between the electrode and itself; and a light-transmitting substrate (8) that faces the second insulator with the first insulators interposed somewhere and with the emitter interposed elsewhere. If the first insulators are extended to reach the light-transmitting substrate on a cross section including the first and second insulators, the emitter and the light-transmitting substrate, the ratio of the cross-sectional area of the emitter to the combined cross-sectional area of the first and second insulators and the light-transmitting substrate is defined so as to fall within a predetermined range.

A light-emitting element (1) includes a light-emitting layer (2) including a phosphor, and at least two electrodes (6, 7). The light-emitting element (1) includes at least two kinds of electrically insulating layers (2, 9) with different dielectric constants. One of the electrically insulating layers (2, 9) is the light-emitting layer (2), and one of the two electrodes (6, 7) is formed in contact with one of the insulating layers. Therefore, it is possible to provide a light-emitting element that can emit light by using surface discharge, is manufactured at low cost, exhibits favorable luminous efficiency, and is to be driven with low power consumption when being applied to a large-screen display.

An image forming apparatus includes a movable image bearing member, a charger means including a charge member for electrically charging the image bearing member with electroconductive particles between the charge member and the image bearing member and a developing member for developing a latent image with toner mixed with electroconductive particles. The latent image is formed on the image bearing member having been charged by the charging means, and a toner image provided by development of the latent image by the developing member is transferred onto a recording material. The electroconductive particles mixed in the toner is carried by the image bearing member and are fed to between the charge member and the image bearing member. The width A, measured in a direction perpendicular to a moving direction of the image bearing member, in which the electroconductive particle are present between the charge member and the image bearing member, a width B in which the developing means is capable of effecting development, and a recording width C of a maximum size recording material, satisfy: A>B≧C.
摘要:
A green sheet including a binder containing an acrylic resin having no polar group and a ceramics material in powder is prepared, and connection via are formed in the green sheet. Further, a conductor layer having virtually no voids is placed on the green sheet and a mask is also placed on the conductor layer. Then, the conductor layer is patterned by wet-etching so that wiring is formed thereon. A plurality of the green sheets thus formed are laminated, and a binding sheet, which contains an inorganic composition that has virtually no sintering shrinkage at the firing temperature of the multi-layered body as a main component, is formed on either both surfaces or one surface of the laminated body, and this is then fired, and thereafter, the binding sheet is removed.
