Abstract:
1. A toner collector comprising: a housing; an inlet port that is opened in the housing and through which toner flows together with an airflow; a fan disposed in the housing, the fan intaking and discharging the airflow having flowed in through the inlet port; a discharge port that is provided to the fan and through which the airflow is discharged; an upstream side filter disposed on an upstream side of the fan in a direction of the airflow, the upstream side filter capturing the toner and allowing passage of the airflow; and a downstream side filter disposed on a downstream side of the discharge port in the direction of the airflow, the downstream side filter allowing the passage of the airflow discharged from the discharge port and capturing the toner, the downstream side filter having a cross section perpendicular to the direction of the airflow that is larger than than the discharge port, the downstream side filter having a facing surface disposed to be perpendicular to a discharge direction of the airflow discharged from the discharge port, and facing the discharge port in the discharge direction, a communication section including a communication space where communication between the discharge port and the downstream side filter is established and where the airflow flows, the facing surface of the downstream side filter facing the communication space; and a communication region changing section that changes an area of a communication region of the facing surface, the communication region being in communication with the communication space, the communication region changing section includes:
