摘要： The image forming apparatus includes an image forming unit, a fixing unit having a heating member, a temperature detector, an acquisition unit, and a controller. When image formation is consecutively performed, and the acquisition unit acquires a first density, which is the density information of the image formed on a k-th recording material, and a second, higher density, which is the density information of the image formed on an l-th recording material, while the image is being fixed on the k-th recording material, the controller controls the power so that the detection temperature becomes a temperature higher than a fixing temperature according to the first density, and lower than a fixing temperature according to the second density. While the image is being fixed on the l-th recording material, the controller controls the power so that the detection temperature becomes the fixing temperature according to the second density.

摘要： An image forming apparatus includes a control unit configured to execute a first mode and a second mode. The first mode is a mode in which a toner image is formed on a sheet at a time when a sheet passes through an image formation position for a first time after detecting a property of the sheet by a detection unit. Wherein the second mode is a mode in which a toner image is not formed on a sheet at the time when the sheet passes through the image formation position for the first time after detecting the property of the sheet by the detection unit and is formed on the sheet at a time when the sheet is conveyed via the second conveyance path and passes through the image formation position for a second time.
