PROBLEM TO BE SOLVED: To provide a toner recovery mechanism allowing achievement of a stable print quality.SOLUTION: A toner recovery device includes: a cleaning mechanism for removing toner remaining on a photoreceptor, from on the photoreceptor: and a toner recovery mechanism for collecting toner 13 removed by the cleaning mechanism and recovering the toner 13 by accumulating the toner 13 into a toner bag 11 installed in a closed case 12. Further, the toner recovery device includes: toner bag pushing-up means 15 which pushes up a lower surface of the toner bag 11 from a bottom of the closed case 12 by an electric device 14; and toner weight estimation means 16 which estimates the weight of toner recovered into the toner bag 11, on the basis of a load of the electric device 14 which is applied when the toner bag 11 is pushed up. |
