摘要： A cover is pivotally supported on the main body frame to close an opening formed on the side of the main body frame, and pivotally supports a sheet convey unit positioned between the cover and the main body frame. A sheet inserted into the main body frame is conveyed along a guide path defined between the main body frame and the convey unit to an image forming section so that one surface of the sheet is printed. Then, the sheet is turned and transferred along the path defined between the cover and the convey unit. The sheet is again conveyed to the image forming section so that the other surface of the sheet is printed.

摘要： An image forming apparatus estimates a temperature at nozzles in consideration of temperature changes in a recording head, by temperature sensors provided at an ink supply port and an ink eject port in the recording head. From the estimated temperature and a temperature difference between when feeding ink and when ejecting ink, a temperature control based on heating/cooling is performed by combining a fan and a heater with heating/cooling based on the peltier element, so as to fall within a drivable temperature range in which the nozzles properly discharge ink.
