    • The image forming apparatus can retain a stable and high image quality for many hours without use of any high precise mechanical parts and without causing any non-uniformity and mal-registration in a color image. In the image forming apparatus, an image recording medium (photosensitive drum) (6a) is driven by a rotative driving mechanism (pulleys and belts) (40a); and an image recording section (print bar) (6c) records an image repeatedly on the rotating image recording medium (6a) in a direction perpendicular to a rotational direction of the image recording medium. The image recorded on the image recording medium (6a) is transcribed onto an image transcribing medium (paper) (22) being fed in the rotational direction of the image recording medium (6a) to form an image. In particular, the apparatus comprises a rotation detecting section (rotary encoder) (6r) for detecting angular travel rates of the image recording medium (6a); and a recording timing control section (5) for controlling recording timing (HSYNC) at which the image is started to be recorded in the direction perpendicular to the rotational direction of the image recording medium (6a), on the basis of the angular travel rates detected by the rotation detecting section (6r).
    • 图像形成装置可以在不使用任何高精度机械部件的情况下保持稳定且高图像质量许多小时,并且不会在彩色图像中引起任何不均匀性和误配准。 在图像形成装置中,图像记录介质(感光鼓)(6a)由旋转驱动机构(滑轮和皮带)(40a)驱动; 并且图像记录部(打印条)(6c)在垂直于图像记录介质的旋转方向的方向上将图像重复地记录在旋转图像记录介质(6a)上。 记录在图像记录介质(6a)上的图像被转录成沿着图像记录介质(6a)的旋转方向馈送的图像转录介质(纸)22,以形成图像。 特别地,该装置包括用于检测图像记录介质(6a)的角行进速率的旋转检测部(旋转编码器)(6r)。 以及记录定时控制部分(5),用于基于角速度速率控制图像开始记录在垂直于图像记录介质(6a)的旋转方向的方向上的记录定时(HSYNC) 由旋转检测部(6r)检测。
