摘要： An image reading apparatus for reading a document image includes: a document feeding tray for placing the document thereon; a first document reading position for reading the first face of the document ejected and conveyed each from the document feeding tray; a document reverse tray for storing the document so that the document having passed through the first document reading position is reversed and conveyed; a stationary document reading position wherein the document having passed through the document reverse tray and having been reversed and conveyed is conveyed to a platen and the stationary document is read; and an image reading unit for reading the document image. The image reading unit stops at the first document reading position to read the first face of the document, and performs scanning movement at the stationary document reading position to read the second face of the document.

摘要： An image forming apparatus for performing thermal fixing of toner images, including a fixing section, a heating section, a power supply section and a control section. The control section controls the power supplying section to start supplying electric power to the heating section, and the control section controls the power supplying section to stop supplying electric power to the heating section after a lapse of a predetermined time interval, based on a thermal response characteristic of a temperature detecting section, even when the temperature of the heating section has not yet reached a target fixing temperature.
