| contents | We study phase separation in the $t-t'-J$ model in which the constraint of no double occupancy due to strong electron correlations leads to effective narrowing of the band width. Using a mean-field approximation, we calculate the compressibility in the normal state and show that the phase separation can be induced by the variation of the band width. |
