ABSTRACT:
In an image formation apparatus, a discomfort probability P, calculated from an expression (a), fulfills a condition (b). Here,in-line-formulae description="In-line Formulae" end="lead"?{circumflex over (P)}im=1/{1+exp [−z]}  (a)in-line-formulae description="In-line Formulae" end="tail"?in-line-formulae description="In-line Formulae" end="lead"?{circumflex over (P)}im≦0.2725·ln(ppm)−0.6331  (b)in-line-formulae description="In-line Formulae" end="tail"?where z=A×sound pressure level i+B×loudness i+C×sharpness i+D×tonality i+E×impulsiveness i+F, i=1, 2, 3, . . . , n, A, B, C, D, and E are regression coefficients of parameters, and F is intercept, and A, B, C, D, E, and F satisfy the inequalities 0.142≦A≦0.183, 0.300≦B≦0.389, 1.097≦C≦1.265, 9.818≦D≦11.516, 2.588≦E≦3.240, −18.844≦F≦14.968, ppm is a printing speed per minute for A4 horizontal size paper.
