Image forming apparatus having a controller for controlling the registration rollers

An image forming apparatus in which a latent image is formed on a rotatable image forming body and a toner image is obtained by developing the latent image and is transferred to a transfer material, said apparatus comprising:

• feeding means for feeding transfer material at a first predetermined speed;
• double feeding preventing means for preventing more than one transfer material from being fed at the same time;
• a pair of registration rollers;
• feed controlling means for stopping the feeding of transfer material by the feeding means when a leading end of the transfer material abuts a nip portion of said pair of registration rollers;
• and
• conveying controlling means for controlling said registration rollers by rotating said registration rollers after said feed controlling means stops the feeding of said transfer material to convey the transfer material to a predetermined position at a second predetermined speed lower than said first predetermined speed and then rotating said registration rollers to convey the transfer material from the predetermined position to a transfer position at a third predetermined speed higher than said second predetermined speed, the third predetermined speed being in synchronism with the speed of the image forming body.
