摘要： A laser scanner control circuit which is used for an apparatus for scanning onto a photo sensitive material by a laser beam and forming and image thereon is constructed as a monolithic driver IC onto a single chip. A reset circuit is provided for a sample-hold circuit so as to minimize the laser power when the image forming apparatus is in a standby mode. A circuit to detect an abnormality of the laser power is further provided. Due to this, the safety of the laser power control of the sample-hold circuit is improved. The operation of the sample-hold circuit can be started at a time point when the laser emitting operation is stable.

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.
