Image forming apparatus

Provided is an image forming apparatus including a fixing unit that fixes a developer image which is formed on a thermoplastic recording medium by performing fixing processing that causes the recording medium on which the developer image is formed to be heated and pressed with transportation based on plural fixation parameters, a detection unit that detects an amount of extension and contraction which occurs in the recording medium by the fixing processing, and a suppression unit that controls at least one of the plural fixation parameters and suppresses the amount of extension and contraction which is detected by the detection unit. 本发明提供种图像形成装置，所述图像形成装置包括：定影单元，其通过基于多个定影参数进行定影处理对形成在热塑性记录介质上的显影剂图像进行定影，定影处理使形成有显影剂图像的记录介质在传送的同时被加热和加压；检测单元，其检测因定影处理而在记录介质中发生的伸缩量；以及抑制单元，其控制多个定影参数中的至少个，并且抑制检测单元所检测到的伸缩量。
