摘要： An emissive element array of a plurality of organic EL elements is arranged linearly on a single-crystal silicon substrate or polycrystalline silicon substrate with a drive circuit including an element switching its respective emissive element. The organic EL emissive elements have an edge emitting structure utilizing light emitted in an edge direction perpendicular to the direction of deposition of electrode layers and organic compound layers, and is constructed such that the emitting area of one emissive element, S, as viewed in the direction of deposition, and the period of emissive elements disposed side by side, d, have the relationship of S>d2. In this way, organic EL techniques can be applied to provide the required amount of light exposure and to produce an exposure device that is small and inexpensive.

Moreover, it is possible to provide a blade which can increase the dimensional tolerance of the inclined section and can be produced easily at a low cost.

摘要： It is an object of the invention that development quality is improved by increasing the amount of charge during the transportation of toner by a toner holding member and decreasing the amount of charge during development for rendering an electrostatic latent image visible. A one-component non-magnetic toner is supplied from a toner supplying unit to the toner holding member such that the toner is electrostatically attracted to adhere to the toner holding member with a large amount of charge. The charge of the toner under transportation is reduced by charge adjusting means such as a conductive roller supplied with a potential from a frictional charging member or a voltage source, whereby the amount of development or the amount of toner adhering to an electrostatic latent image is increased and development quality is improved.
