Abstract For q ∈ (0, 1) let the q-difference operator be defined as follows q f (z) = f (qz) - f (z) {z (q - 1) } (z U), where U denotes the open unit disk in a complex plane. Making use of the above operator the extended Ruscheweyh differential operator R qλ f is defined. Applying R qλ f a subfamily of analytic functions is defined. Several interesting properties of a defined family of functions are investigated.
