Abstract
Abstract In a color image forming device including a modification executing section 12, a recording medium indicating section 14, an optimized data section 16, and an optical system 18, the modification executing section 12 modifies the color image data into the optimized data to be stored in the optimized data section 16, in response to indication of a type of a recording medium from the recording medium indicating section 14. The optical system 18 carries out exposure in response to the data from the optimized data section 16. Thus, an image having a uniform quality is formed in color image formation on various types of recording media.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
102 words
A color image forming device characterized by: modification executing means (12) for modifying color image data in response to an indication of the type of a recording medium on which a color image is to be formed; recording medium indicating means (14) for supplying said indication of the type of said recording medium to said modification executing means (12); optimized data storing means (16) for storing said image data, as optimized data, after modified by said modification executing means (12); and optical means (18) for carrying out exposure in accordance with said optimized data supplied from said optimized data storing means (16).
Claim 2
Dependent Claim
