We show that an inflationary background might be realized by using any p-form
non-minimally coupled to gravity. Standard scalar field inflation corresponds
to the 0-form case and vector inflation to the 1-form. Moreover, we show that
the 2- and 3-form fields are dual to a new vector and scalar inflationary
theories where the kinetic terms are non-minimally coupled to gravity.
