Abstract:
A image forming apparatus comprising:writing means for an electrostatic image onto a photoconductor by laser light;mode setting means for setting a writing mode between a one dot multi-level image mode and a binary dots image mode according to a type of image to be formed;control means for controlling a writing laser power of said writing means according to the writing mode set by said mode setting means and for controlling the writing laser power for the binary dots image mode to be greater than the writing laser power for the one dot multi-level image mode,wherein said control means controls the writing laser power such that an exposure potential is 1/5-1/10 of a charged potential for the one dot multi-level image mode and an exposure potential is 1/8-1/16 of a charged potential for the binary dots image mode.
