An image forming apparatus includes a carriage mounted with a recording head, a carriage driving mechanism including a motor for reciprocatingly moving the carriage, a sheet conveying mechanism that conveys the sheet in a direction orthogonal to a moving direction of the carriage, a sheet guide member that has a guide section arranged below the recording head and opposed to the recording head and in which the sheet passes over the guide section, a sheet stacking unit that stacks and stores the sheet before printing, a first conveying path that conveys the sheet from this sheet stacking unit while causing the sheet to pass below the recording head, a second conveying path that conveys the sheet from this first conveying path to a space between the recording head and the sheet guide member while reversing the sheet, a third conveying path that conveys the sheet from the first conveying path to a temporary storing unit in a state in which a front-to-rear direction of the sheet is maintained, a fourth conveying path that conveys the sheet from the temporary storing unit to the space between the recording head and the sheet guide member in a state in which the front-to-rear direction of the sheet is maintained, a first switching mechanism that switches a conveying direction of the sheet fed from the first conveying path between the second conveying path and the third conveying path, and a second switching mechanism that guides the sheet fed from the second conveying path or the third conveying path to the fourth conveying path side.
