ABSTRACT:
When a binary image signal or multivalued image signal is input to form an image, if the binary image signal is input, one of the line width output characteristic previously stored in memory is set and displayed. If the multivalued image signal is input, one of the density output characteristic previously stored in the memory is set and displayed. Each of the line width output characteristic and the density output characteristic can be changed by the operator. The line width output characteristic is changed by changing the development bias voltage, and the density output characteristic is changed by changing the .gamma.-table.
