Abstract
A toner collector includes a housing, an inlet port, a fan, a discharge port, a first upstream side filter, and a downstream side filter. The inlet port is opened in the housing. The fan is disposed in the housing, and intakes and discharges the airflow having flowed in through the inlet port. The discharge port is provided to the fan. The first upstream side filter is disposed on an upstream side of the fan in a direction of the airflow, and captures the toner and allows passage of the airflow. The downstream side filter is disposed on a downstream side of the discharge port in the direction of the airflow, and allows passage of the airflow discharged from the discharge port and captures the toner. The downstream side filter has a larger cross-sectional area of a cross section perpendicular to the direction of the airflow than the discharge port.
