Abstract
An image forming apparatus includes a plurality of temperature-influence members, a first-point temperature acquisition unit, a second-point temperature estimation unit, and a controller. The plurality of temperature-influence members have influence on a temperature of a recording medium on which an image is formed. The first-point temperature acquisition unit is configured to detect or estimate a temperature of the recording medium at a first point. The second-point temperature estimation unit is configured to estimate a temperature of the recording medium at a second point, based on a detection result of at least one of a temperature of the recording medium at a point different from the second point and a temperature of a member or atmosphere. The controller is configured to control the plurality of temperature-influence members, based on an acquisition result from the first-point temperature acquisition unit and an estimation result from the second-point temperature estimation unit.
