Abstract
An image forming apparatus includes a flow passage associated with a direction of flow and a particle collecting device including a filter to collect particles in a fluid passing through the flow passage in the direction of flow. The flow passage includes a curved portion, and a distribution in particle collecting performance of the filter in a direction perpendicular to the direction of flow results from the curved portion of the flow passage.
