  We present a BRST symmetric gaugeon formalism for the two-form gauge fields.
A set of vector gaugeon fields is introduced as a quantum gauge freedom. One of
the gaugeon fields satisfies a higher derivative field equation; this property
is necessary to change the gauge-fixing parameter of the two-form gauge field.
A naive Lagrangian for the vector gaugeon fields is itself invariant under a
gauge transformation for the vector gaugeon field. The Lagrangian of our theory
includes the gauge-fixing terms for the gaugeon fields and corresponding
Faddeev--Popov ghosts terms.
