摘要： An image forming apparatus which converts character or pattern information into bit map information (pixel information) and forms an image based thereon. The image forming apparatus includes a light-beam generator for generating a modulated light beam, a light-beam deflector for scanning an image carrier, a device for feeding a sheet to registration rollers and a driver for driving the image carrier. A time period is provided to operate the light-beam deflector and the feeding device before the driver starts to drive the image carrier to form an image.
