AI Technical Summary
Technical Problem
Existing image forming apparatuses struggle to efficiently collect and reduce ultrafine particles with particle diameters of 100 nm or less over a long period, especially when using filters like nonwoven fabrics or sponges.
Method used
The image forming apparatus incorporates a mesh member in the air intake of the exhaust device, with a larger mesh size at the second intake port compared to the first, to efficiently collect ultrafine particles while minimizing pressure loss.
Benefits of technology
This configuration allows for the efficient collection and reduction of ultrafine particles over a long period, with improved pressure loss management compared to traditional filter systems.

Abstract
To provide an image forming apparatus capable of efficiently capturing and reducing ultrafine particles with a particle size of 100 nm or less for a long period compared to the case of arranging a filter such as non-woven fabric and sponge as a member for collecting fine particles.SOLUTION: An image forming apparatus 1 includes: a housing 10; a fixing unit 5 that is placed in the housing 10 for heating an unfixed image formed of developer and fixing the same onto a recording medium 9; an intake port 62 for sucking the air heated in fixing unit 5; an exhaust port 63 for discharging the air sucked through the intake port 62 to the outside of the housing 10; an exhaust unit 6 that has a flow path part 64 forming an air flow path space C from the intake port 62 to the exhaust port 63; and a mesh material 7 that is provided at the intake port 62 or the like for collecting fine particles in the sucked air.SELECTED DRAWING: Figure 1
