摘要： A photo conductor and exposure integrally-formed type apparatus is of a drum type, and is rotated at a fixed speed in a clockwise direction. A residual toner attached to a surface of the photo conductor is removed by a cleaner, and a charging device applies a charge load uniformly to a surface of the photo conductor layer so as to charge the photo conductor layer. A light emitting layer exposes the photo conductor layer in a luminous area from an inner side, and forms a latent image on the photo conductor layer. The latent image formed on the photo conductor layer is developed by toner by a developing device, and forms an apparent image by the toner attached to the latent image. Further, the toner image appearing on the photo conductor layer is transferred on a recording medium by a transfer device. Accordingly, since no movement exists between an exposure point and an image forming point in the luminous area, an image deterioration caused by the movement is not generated.
摘要翻译： 光导体和曝光一体成形型设备是鼓型，并且以顺时针方向以固定速度旋转。 附着在光电导体表面上的残留调色剂通过清洁剂去除，并且充电装置将电荷负载均匀地施加到光导体层的表面，以对光导体层充电。 发光层从内侧将发光区域的光导体层曝光，并在光导体层上形成潜像。 形成在光导体层上的潜像由显影装置通过调色剂显影，并通过附着在潜像上的调色剂形成表观图像。 此外，出现在光导体层上的调色剂图像通过转印装置在记录介质上转印。 因此，由于曝光点和发光区域中的图像形成点之间没有移动，所以不会产生由移动引起的图像劣化。
