We present a universal democratic Lagrangian for the bosonic sector of ten-dimensional type II supergravities, treating ``electric'' and ``magnetic'' potentials of all Ramond-Ramond (RR) fields on equal footing. For type IIB, this includes the five-form whose self-duality equation is derived from the Lagrangian. We also present an alternative form of the action for type IIB, with manifest SL (2, R) symmetry.
