We show that every continuous Jordan derivation from U to X is a derivation, where U is a ϕ-Johnson amenable Banach algebra in which ϕ is a non-zero multiplicative linear functionals on U, and X is a Banach U-bimodule such that a:x = ϕ(a)x for all a 2 U, x 2 X or x:a = ϕ(a)x for all a 2 U, x 2 X. Then w
