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.
Claims15
An image forming apparatus comprising:
- a flow passage to define a direction of flow of a fluid passing through the flow passage, wherein the flow passage includes a curved portion;
- and
- a particle collecting device installed in the flow passage, the particle collecting device comprising a filter to collect particles contained in the fluid,
- wherein a distribution in particle collecting performance of the filter in a direction perpendicular to the direction of flow corresponds to:
- a distribution in flow velocity of the fluid in the direction perpendicular to the direction of flow;
- or
- a distribution in average particle size of the particles contained in the fluid passing through the flow passage, and
- wherein the distribution in particle collecting performance is generated due to the curved portion of the flow passage.
