L'objectif principal de ce travail est d'établir un théorème d'existence de type Peano pour un problème aux valeurs initiales faisant intervenir une dérivée fractionnaire, puis, comme conséquence, de donner une réponse partielle à l'existence locale d'une solution continue du problème aux valeurs initiales suivant :

{Dxqu(x)=f(x,u(x)),u(0)=b,(b≠0).
De plus, nous étudions les propriétés géométriques des solutions pour quelques cas particuliers.

The first aim of this work is to establish a Peano-type existence theorem for an initial value problem involving a complex fractional derivative, and then, as a consequence of this theorem, to give a partial answer for the local existence of the continuous solution to the initial value problem:

{Dxqu(x)=f(x,u(x)),u(0)=b,(b≠0).
Moreover, for some special cases of the problem, we investigate the corresponding geometric properties of the solutions.
