摘要： An image forming apparatus includes a plurality of recording heads arranged in parallel along a scanning direction perpendicular to a direction of transferring a recording medium to perform a recording movement for recording an image selected from a single-color image and a multicolor image in accordance with the image data. The recording heads record the multicolor image during a period of moving in one direction and record the single-color image during a period of moving in two opposite directions.

摘要： An image forming apparatus includes a specific color image forming station for forming a black image and one or more non-specific color image forming stations for forming images of colors other than black, the photosensitive drum of the specific color image forming station is located vertically downward of the photosensitive drums of the non-specific color image forming stations, and the capacity of the black toner cartridge of the specific color image forming station is made larger than those of the toner cartridges of the non-specific color image forming stations. With this arrangement, the frequency of replacement of the black toner cartridge can be reduced without adversely affecting the size of an apparatus main body.

摘要： In a serial page printer for printing an image line by line by scanning a printing head, even if a motor for driving a roller for conveying a printing medium is rotated by a predetermined amount, the printing medium is not conveyed by a predetermined amount depending on decentering of the roller, the position of the printing medium, and the like, resulting in a printing error. In order to prevent this, a predetermined position of the roller is brought into contact with each line of a printing medium. For this purpose, an apparatus of the present invention detects that the position of the printing medium and the state of the roller are in a predetermined state. Therefore, a line subjected to printing and the state of the roller have a predetermined relationship on any page, and the printing medium can be conveyed by a predetermined amount for each line by adjusting the rotational amount of the roller for each line in advance.
