Abstract: PROBLEM TO BE SOLVED: To improve durability of a device by providing an element for supporting an organic compound layer between a positive electrode layer and a negative electrode layer on a substrate and covering it with a protective film of tantalum oxide. SOLUTION: A positive electrode layer 2, a positive hole transport layer 4, an electron transport layer 5, a negative electrode layer 3, and a protective layer 6 are laminated in the order on a substrate 1. The protective layer 6 covers the luminous element and protects an upper surface of the luminous element, having this lamination structure from moisture and oxygen in the atmosphere. The substrate 1 is provided for forming a luminous element on its surface, for example, a plate, sheet, or film formed from transparent insulating material of glass, such as soda lime glass or the like or synthesized resin. A lower surface side of the luminous element is protected from moisture and oxygen in the atmosphere by the glass substrate 1. High level of shut off from moisture and oxygen is provided by forming the protective film 6 of a tantalum oxide film. The protective film 6 of amorphous makes it difficult for cracks to enter. The film 6 can have higher level of shut off, since it has a higher membrane packing rate.

Abstract: PROBLEM TO BE SOLVED: To reduce the number of the driving wirings of a printer head and the number of chips of a driving circuit by using a specific one-chip light emitting element array in stead on a conventional combining-type LED, and to dissolve the variation of light emitting characteristic. SOLUTION: A light emitting element array for yellow 200a, a light emitting element array for magenta 200b, the light emitting element array for cyanogen 200c and the light emitting element array for black 200d use one-chip light emitting element arrays arranged by covering the whole area of a main scanning distance D in a main scanning direction with respect to the rotation movement of photosensitive drums 1a to 1d. The one-chip light emitting element arrays use what are prepared from a single substrate and respectively cut-divided into four. The cost of the light emitting element array part of an image forming device is reduced to improve color reproducibility at a main scanning direction. In addition, as the light emitting characteristics of the respective single-chip light emitting element arrays are nearly equal, characteristic compensation between the respective element arrays is omitted.

Abstract: PROBLEM TO BE SOLVED: To obtain direct injection type electrification excellent in the uniformity of electrification and stable over a long period, even if a simple member such as an electrifying roller is used as a contact-electrifying member by interposing conductive grains in the nip part between an electrifying member and a body to be electrified. SOLUTION: In an electrifying nip part (n) being the nip part between a photoreceptor 1 as the body to be electrified and the electrifying roller 2 as the contact-electrifying member, the contact-electrification of the photoreceptor 1 is attained in a coating state with electrification accelerating grains 3. Thus, in the electrifying nip part (n), the electrifying roller 2 can come into contact with the photoreceptor 1 which having a difference between their speeds. Moreover, the electrifying roller 2 comes into close contact with the photoreceptor 1 with the electrification accelerating grains 3, that is, the grains 3 existing in the electrifying nip part (n) being the nip part between the roller 2 and the photoreceptor 1 rub the surface of the photoreceptor, without a gap, to directly inject en electric charge into the photoreceptor 1. Therefore, high electrifying efficiency which can not be obtained by conventional roller electrification can be obtained and a voltage almost equal to that applied to the electrifying roller can be applied to the photoreceptor 1.
