图像形成装置
摘要：
本发明提供的图像形成装置包括：壳体；壳体内的薄片体输送通道；调色剂包含部，包含调色剂，与薄片体输送通道的第一位置相对；定影单元，在第一位置下游侧的第二位置与薄片体输送通道相对，实施定影处理；定影外壳，收纳定影单元，具有与调色剂包含部相对的壁部；隔热构件，在壁部和调色剂包含部间进行遮挡，一端与薄片体输送通道相对，另一端向离开薄片体输送通道方向延伸；第一排热风路，设在隔热构件与调色剂包含部之间；第二排热风路，在所述另一端侧与第一排热风路连通；以及第三排热风路，设在壁部与隔热构件之间，具备与薄片体输送通道相对的开口和与第二排热风路连通的连通口。由此，能提高定影单元与其周边装置间的隔热效果。
摘要（英）：

An image forming apparatus (1) includes a housing (10), a sheet conveyance path (22F), a toner containing unit (50), a fixing unit (40), a fixing housing (40H), a heat insulation member (10S), a first hot air exhaust passage (r11), a second hot air exhaust passage (r12) and a third hot air exhaust passage (r21). The fixing housing (40H) houses the fixing unit (40) and includes a wall portion (40L) facing the toner containing unit (50). The heat insulation member (10S) shields between the wall portion (40L) and the toner containing unit (50). The first hot air exhaust passage (r11) is arranged between the heat insulation member (10S) and the toner containing unit (50). The second hot air exhaust passage (r12) communicates with the first hot air exhaust passage (r11). The third hot air exhaust passage (r21) is arranged between the wall portion (40L) and the heat insulation member (10S) and includes an opening (13) facing the sheet conveyance path (22F) and a communication port (77) communicating with the second hot air exhaust passage (r12).
