Abstract: Let k, m be two positive integers with m≤k and let F be a family of zero-free meromorphic functions in a domain D, let h(z)≡0 be a meromorphic function in D with all poles of h has multiplicity at most m. If, for each f ∈ F , f(k)(z) = h(z) has at most k-m distinct roots(ignoring multiplicity) in D, then F is normal in D. This extends the results due to Chang[1], Gu[3], Yang[11] and Deng[1] etc.
