PROBLEM TO BE SOLVED: To suppress thickening of lines without reducing the performance of toner.SOLUTION: When the line width of magenta (M), cyan (C), and yellow (Y) toners is D and the layer thickness of the toners is LT, and the line width of a binder toner (B, WB) is d, a binder toner line width correction part 45 derives the line width d of the binder toner (B, WB) according to d=a1×D (a1=A/LT, and A=constant) in a section where the line width D of the magenta (M), cyan (C), and yellow (Y) toners is 0≤D<α. Meanwhile, in a section where the line width D of the magenta (M), cyan (C), and yellow (Y) toners is equal to or larger than α, the binder toner line width correction part derives the line width d of the binder toner (B, WB) according to d=a2×D-b (a2=constant, b=B×LT, and B=constant).SELECTED DRAWING: Figure 2 【課題】トナー性能を低下させることなく、線太りを抑える。【解決手段】バインダトナー線幅補正部４５は、マゼンタ（Ｍ）、シアン（Ｃ）及びイエロー（Ｙ）の線幅をＤ、層厚をＬＴ、バインダトナー（Ｂ、ＷＢ）の線幅をｄとすると、マゼンタ（Ｍ）、シアン（Ｃ）及びイエロー（Ｙ）の線幅Ｄが０≦Ｄ＜αの区間では、ｄ＝ａ１×Ｄ（ａ１＝Ａ／ＬＴであり、Ａ＝定数）に従ってバインダトナー（Ｂ、ＷＢ）の線幅ｄを導出する。また、マゼンタ（Ｍ）、シアン（Ｃ）及びイエロー（Ｙ）の線幅Ｄがα以上の区間では、ｄ＝ａ２×Ｄ−ｂ（ａ２＝定数、ｂ＝Ｂ×ＬＴ、Ｂ＝定数）に従ってバインダトナー（Ｂ、ＷＢ）の線幅ｄを導出する。【選択図】図２
