Abstract:
1. An image forming apparatus comprising: a multiplying unit configured to multiply a first clock to drive the image forming apparatus, thereby forming a second clock; a first holding unit configured to hold a frequency of a third clock used by a print unit in the image forming apparatus; a second holding unit configured to hold a magnification setting of the multiplying unit; a third holding unit configured to hold a resolution to which the print unit corresponds; a fourth holding unit configured to hold a micro zoom ratio; a multiplication ratio control unit configured to set a magnification of the multiplying unit on the basis of the values held in the first to fourth holding units; a discriminating unit configured to discriminate whether or not a pixel is a target pixel to which a micro zoom is executed by using the value held in the fourth holding unit; a forming unit configured to switch a count comparison value of the second clock formed by the multiplying unit in accordance with a discrimination result of the discriminating unit, thereby forming the third clock; and a unit configured to form a pixel segment on the basis of image data of the target pixel corresponding to the discrimination result of the discriminating unit and insert the formed pixel segment in accordance with a period of the third clock.
