Abstract
An image forming apparatus includes a cyclone portion, a bin, a filter, a fan, a detector and a corrector. The cyclone portion separates toner from air containing dispersed toner by centrifugation. The bin stores the toner separated by the cyclone portion. The filter filters the air from which the toner has been separated by the cyclone portion. The fan generates an air flow for discharging the air which has passed through the filter. The detector detects the bin being full of the toner based on a change of a rotation speed of the fan. The corrector corrects the rotation speed of the fan based on a change of a physical property of the air which corresponds to a change of an environmental condition in image formation.
