Let D α f ( z ) be the Ruscheweyh derivative defined by using the Hadamard product of f ( z ) and z / ( 1 − z ) 1 + α . Certain new classes S α * and K α are introduced by virtue of the Ruscheweyh derivative. The object of the present paper is to establish several interesting properties of S α * and K α . Further, some results for integral operator J c ( f ) of f ( z ) are shown.
