Abstract: A method and apparatus of forming an image includes reading an original with a first resolution. An original is read with a second resolution which is different from said first resolution. The image information read with the first resolution and the second resolution is converted into image information of a third resolution for image forming. An image is formed with the third resolution based on the image information converted by the conversion.

Abstract: A four-line CCD sensor is structured by line sensors R, G, B in which color filters are respectively disposed on surfaces of light receiving elements, and a line sensor BK at which no color filter is disposed. Amplitudes of signals which are outputted from the line sensors R, G, B at a time of reading a color document, and an amplitude of a signal which is outputted from the line sensor BK at a time of reading a monochrome document are adjusted so as to be substantially equal to one another. In a case in which a color document is read, outputs of the line sensors R, G, B are selectively provided, and in a case in which a monochrome document is read, output of the line sensor BK is selectively provided.
