A cleaning device in an image-forming machine. A supporting frame structure includes a toner recovery box receiving space and a toner recovery box to be inserted into the receiving space. A toner inlet extending in the front-rear direction is formed in the toner recovery box. The cleaning device further includes a cover for recovering or closing the toner inlet at the time of withdrawing the toner recovery box from the receiving space, thereby preventing scattering of toner from the toner inlet.
