Abstract:
An image forming apparatus comprising:first transport means for transporting a sheet member;second transport means disposed upstream of said first transport means for transporting a sheet member to said first transport means;a motor operable at a rotational speed;a first clutch for transmitting the drive force of said motor to said first transport means;a second clutch for transmitting the drive force of said motor to said second transport means;control means for controlling said motor, said first clutch and said second clutch in such a way that the rotational speed of said motor changes while said first clutch is disengaged and said second clutch is engaged, thereby changing the transport speed of said second transport means from a speed faster than that of said first transport means to a speed slower than that of said first transport means before said sheet member hits said first transport means, and the end portion of said sheet member hits said first transport means at rest so that the sheet member forms a loop; andimage forming means for forming an image on a sheet member transported by said first transport means.
