Abstract:
An image forming apparatus, comprising:writing means for writing an electrostatic image onto a photoconductor by impinging a writing laser light onto the photoconductor; resolution setting means for setting an image writing resolution; control means for controlling a writing laser power of said writing laser light generated by said writing means according to the image writing resolution set by said resolution setting means and for controlling the writing laser power for a high resolution mode to be greater than the writing laser power for a low resolution mode, wherein said control means controls the writing laser power according to an expression: 1<Pb/Pa&lE;b/a, â€ƒwherein a: a resolution value of the low resolution mode; b: a resolution value of the high resolution mode; Pa: a writing laser power for the low resolution mode; Pb: the writing laser power for the high resolution mode.
