We consider a static self-gravitating charged perfect fluid system in the Einstein\char21{}Maxwell theory. Assume Maxwell's equation and the Einstein constraint equation are satisfied and the temperature of the fluid obeys Tolman's law. Then, we prove that the extrema of total entropy implies other components of Einstein's equation for any variations of metric and electrical potential with fixed boundary values. Conversely, if Einstein's equation and Maxwell's equations hold, the total entropy achieves an extremum. Our work suggests that the maximum entropy principle is consistent with Einstein's equation when an electrostatic field is taken into account.
