A sheet discharging device includes a shift tray 202 on which a sheet P1 is stacked, a discharging roller 6 that discharges a sheet P2 onto the shift tray 202, a blowing device 230 that sends air to a lower surface of the sheet P2 discharged by the discharging roller 6, a blocking member 231 that blocks air sent to the lower surface of the sheet P2 from a blowing port 230-2 of the blowing device 230, and a control unit that controls the blocking amount of the blocking member 231. The blocking amount is determined based upon sheet information including sheet-type information, sheet-size information, and sheet-thickness information, for example.
Image forming apparatus
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.
Image forming apparatus
An image forming apparatus includes an image forming portion, a tray rotatably provided on a side surface of a main assembly and including a stacking surface, a feeding portion; and a blowing fan mounted on the tray and generating air blown to a side end of a sheet in a sheet widthwise direction perpendicular to a feeding direction of the sheet by the feeding portion. The blowing fan is disposed on an opposite side to a side where the sheet is stacked on the stacking surface so that a position of at least a part of the blowing fan with respect to the sheet widthwise direction is overlapped with a position of the stacking surface with respect to the sheet widthwise direction.
