    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: An image production apparatus includes at least one image production unit having a latent image forming device for forming a latent image on an image carrying member and a developing device for attaching toner to the latent image formed by the latent image forming device. A toner image formed by the image production unit is transferred to a transfer medium to produce an image. The image production apparatus further includes a periodicity giving device for giving periodicity to movement in a main scanning direction of the image carrying member or transfer medium. According to this periodicity, the movement time from an image forming position to a transfer position, or the movement time of a transfer medium between adjacent transfer positions is set equal to an integral multiple of the period.
