Abstract:
An image forming apparatus capable of setting a plurality of image forming speeds includes a transfer unit configured to transfer an image formed on an image carrier onto a sheet, a paper feed unit configured to feed the sheet, and a control unit configured to control the conveyance speed of the sheet to accelerate and decelerate without stopping the sheet in a section between the paper feed unit and the transfer unit to synchronize the sheet with the image formed on the image carrier. The control unit changes paper feed timing from the paper feed unit according to the image forming speed if the image forming speed is predetermined.
