In this paper, when an entire function and the linear combination of its derivatives with small functions as its coefficients share one value CM and another value IM is studied. We also resolved the question when an entire function and its derivative share two values CM jointly. Some of the results remain to be valid if is meromorphic and satisfying as and the values are replaced by small functions of .
