<P>PROBLEM TO BE SOLVED: To provide an image printing apparatus which can print a toner image at a prescribed position on a sheet and cope with high-speed image printing as well. <P>SOLUTION: The image printing apparatus is provided with a control unit which performs control to: start driving a registration roller at a first sheet convey speed higher than a linear speed of a surface of an image carrier; measure a time required until a leading end of a conveyed sheet is detected by a sensor which detects a sheet after a driving signal for starting driving of the registration roller is output; compare the measured time with a reference time, determine, on the basis of a comparison result; determine a timing at which the sheet convey speed of the registration roller is reduced from the first sheet convey speed to a second sheet convey speed which is the same as the linear speed of the surface of the image carrier; reduce the sheet convey speed of the registration roller from the first sheet convey speed to the second sheet convey speed at the determined timing; and convey the sheet to an image transfer position at the second sheet convey speed. <P>COPYRIGHT: (C)2007,JPO&INPIT |
