摘要： An image forming apparatus includes an image fixing unit to pass a sheet carrying an unfixed toner image on a first side. The image fixing unit includes: a first fixing section adjacent to the first side of the sheet; a first heating section to heat the first fixing section; a second fixing section adjacent to a second side opposite to the first side of the sheet; and a second heating section to heat the second fixing section. The image forming apparatus further includes: sheet feeding trays holding sheets; a storage unit storing fixing temperatures of the fixing sections preset for each type of the sheets in the sheet feeding trays; and a controller to select standby temperatures from the fixing temperatures, based on temperature profiles of the fixing sections, and to instruct the heating sections to respectively maintain the fixing sections at the selected standby temperatures during a standby mode.
