  • Publication number: 20240025689
    Abstract: An image forming apparatus includes an ejection port, a stacker, a fan, and a duct. From the ejection port, a sheet is ejected to an ejection space in an ejection direction. The stacker stacks the sheet ejected from the ejection port, and the ejection space is disposed above the stacker. The fan is disposed outside the ejection space to suck air. The duct is connected to the fan. The duct has an exhaust port and a guide. The exhaust port is disposed above the ejection port and downstream from the ejection port in the ejection direction to exhaust the air from the exhaust port toward an upper face of the sheet in the ejection space. The guide connects the fan and the exhaust port to guide the air from the fan to the exhaust port.
