Abstract
We present a mathematical model of how feeling of inequity toward a society is generated in interactive processes among actors. The model is constructed by developing and combining two preceding models: one is Fararo's model of image formation of stratification; the other is status value formulation of distributive justice. In the present model, we assumed that images of stratification are formed depending on actors' position within input-outcome system and on their first encounter with other actors. Within images actors are assumed to make overall judgment about equitableness of input-outcome system in a society. A standard of justice judgment is given by the ratio of the actual share to the just share. We have derived several implications about what type of actors feel more inequitable in the system.
