摘要： The apparatus is adapted to deflect a light beam from a laser light source for each of the color components by means of a deflection mirror surface which oscillates, thereby making the light beam reciprocally scan in a main scanning direction. In this apparatus, however, only a light beam SL which scans in a first direction (+X) of the main scanning direction is irradiated in an effective image region on a photosensitive member, so as to form a latent image thereon. The resultant latent image is developed to form a toner image. Since image formation is performed using only the light beam SL which scans in the first direction (+X), the images may be formed at the consistent density irrespective of the image types. Furthermore, the scanning directions of the light beams SL for all the color components are uniformly defined to be the first direction (+X), so that the toner images of the respective colors may maintain the consistent density.

摘要翻译： 该装置适于通过振荡的偏转镜面来偏转来自激光光源的每个颜色分量的光束，从而使光束在主扫描方向上往复扫描。 然而，在该装置中，只有在主扫描方向的第一方向（+ X）上扫描的光束SL被照射在感光构件上的有效图像区域中，以便在其上形成潜像。 显影所得潜像以形成调色剂图像。 由于仅使用沿第一方向（+ X）扫描的光束SL执行图像形成，所以可以以一致的浓度形成图像，而与图像类型无关。 此外，用于所有颜色分量的光束SL的扫描方向被均匀地限定为第一方向（+ X），使得各种颜色的调色剂图像可以保持一致的密度。

摘要： An image forming apparatus includes an image carrier, a transfer roller, a transfer roller position detector and a controller. The transfer roller includes a concaved portion formed on a circumferential surface thereof with the concaved portion having a width in the circumferential direction larger than a width of a transfer nip formation area formed between the image carrier and the transfer roller in the circumferential direction. The transfer roller includes an elastic member disposed on the circumferential surface thereof. The transfer roller position detector is configured and arranged to detect a rotational position of the transfer roller. The controller is configured to stop rotation of the transfer roller in a state in which the concaved portion is located at the transfer nip formation area on the basis of the rotational position of the transfer roller.
