Abstract
An image forming apparatus capable of accurately forming an image in a predetermined position on a sheet. An image forming unit forms a toner image on a drum. The toner image is transferred onto a belt. A motor drives the belt to convey the toner image to a transfer position where the toner image is transferred onto a sheet. An image position-detecting section detects that a patch image indicating the position of the toner image on the belt has reached a detection position upstream of the transfer position in an image conveying direction. A sheet position-detecting section detects that the leading edge of the sheet has reached a detection position upstream of the transfer position in a sheet conveying direction. An image speed-setting section controls the conveying speed of the belt based on timings of detection by the respective image position-detecting and sheet position-detecting sections.
