Image forming apparatus having a controller for controlling the registration rollers

摘要

An image forming apparatus including a double feeding preventing mechanism which is arranged at an outlet side of a sheet feeding unit so that only one transfer material is fed, a sheet-feed controller which is stopped immediately after a leading end of the transfer material fed from the sheet feeding unit abuts against a nip portion between a pair of registration rollers, and a conveying controller for controlling rotation of the registration rollers such that the registration rollers are rotated after a sheet feeding operation is stopped so as to convey the transfer material to a predetermined position at low speed and are then rotated to convey the transfer material from the predetermined position to a transfer position in synchronism with a latent image formation timing.
