La présente invention concerne un système de récipient de toner, tel qu'une cartouche de toner, comprenant un logement doté d'un premier réservoir pour contenir du toner et d'un second réservoir pour recevoir du toner provenant du premier réservoir et pour transférer le toner vers un appareil de formage d'image ; et un mécanisme de transfert de toner doté d'un organe rouleau rotatif comportant à sa surface un renfoncement défini par une surface concave présentant un rayon de courbure. L'organe rouleau peut tourner depuis une première position où le renfoncement est ouvert vers le premier réservoir, vers une seconde position où le renfoncement est ouvert vers le second réservoir, pour transporter le toner du premier réservoir vers le second réservoir grâce à la rotation de l'organe rouleau depuis la première position vers la seconde position.
