    • An image forming apparatus is provided which can form an image of excellent picture quality in which a streak does not appear at a specified position in a main scanning direction. A reading control apparatus includes an illuminator to irradiate an illumination light to a document of a reading object, a CCD sensor that includes a plurality of light-receiving elements arranged in one line to receive the illumination light reflected by the document, and sequentially outputs electric signals stored in the light-receiving elements, a read control part that acquires, with respect to the electric signals of each line generated by the CCD sensor, electric signals by reading the electric signals starting from an electric signal corresponding to a position outside one end, in a main scanning direction, which is one of both ends of the document of the reading target in the main scanning direction and is the end where an electric signal is outputted from the CCD sensor at an earlier timing, a pre-processing part to perform a specified pre-process on the electric signals acquired by the read control part, and an image output control part that removes, with respect to the electric signals of each line, electric signals corresponding to a range outside the one end from the electric signals processed by the pre-processing part, acquires electric signals starting from the electric signal corresponding to the one end, and outputs only the acquired electric signals to outside.
    • 提供一种图像形成装置,其可以形成在主扫描方向上的特定位置处不出现条纹的优异图像质量的图像。 一种读取控制装置,包括将照明光照射到读取对象的原稿的照明装置,CCD传感器,其包括以一行布置的多个受光元件,以接收由原稿反射的照明光,并依次输出电 存储在光接收元件中的信号,读取控制部分,通过从对应于一端外部的位置的电信号读取电信号,获取关于由CCD传感器产生的每行的电信号的电信号 在作为主扫描方向的读取对象文件的两端之一的主扫描方向上,是在较早的时刻从CCD传感器输出电信号的结束,预处理部分 对由读取控制部分获取的电信号执行指定的预处理,以及图像输出控制部分,其相对于该ele 每条线的ctric信号,与从预处理部分处理的电信号相对应的一端范围的电信号,从与该一端相对应的电信号开始获取电信号,并将所获取的电信号仅输出到 外。
