Abstract

An image forming apparatus includes a fixing speed setting unit for selectively setting the fixing speed in accordance with a desired mode of operation, a fixing unit for fixing a reproduced image of an original formed on a image forming medium at a variable fixing speed in accordance with the fixing speed setting unit, and a scanning unit provided with opto-electrical elements arranged in one line extended laterally to a predetermined scanning direction for optically receving an image of the original through the opto-electrical elements. The opto-electrical elements are carrying out a scanning operation in the predetermined scanning direction with varied scanning speed by changing a sweep spacing of an image data with averaging every N line of the image data in accordance with the operation mode with using every N-1 lines of the image data to reproduce the image of the original on the image forming medium.
