A toner collecting device including: a centrifugation cylinder configured to be introduced with an airflow containing a toner and configured to centrifugally separate the toner; an airflow inlet; an airflow outlet; a toner collector that is located at a lower end of the centrifugation cylinder configured to collect the toner separated in the centrifugation cylinder; and a suction unit configured to suction an inside of the centrifugation cylinder through the toner collector and comprising a filtration filter configured to filter out the toner. The ratio of a suction quantity QBD (m/min) of the airflow suctioned to an introduction quantity Qin (m/min) at which the airflow containing the toner is introduced is more than 0% and 30% or less. The ratio of a filtration area (m) of the filtration filter to the suction quantity QBD (m/min) of the airflow suctioned is 0.4 or more and 4.0 or less.
