IMAGE FORMING APPARATUS AND METHOD FOR CONTROLLING IMAGE FORMING APPARATUS

PROBLEM TO BE SOLVED: To reduce a failure in fixing in an image forming apparatus including a fixing device that performs variable control of fixing pressure.SOLUTION: An image forming apparatus comprises: a fixing device 20 that conveys a recording medium P carrying a toner image T to a nip part formed between a fixing roller 21 and a pressure roller 22 to fix the toner image T to the recording medium P; fixing pressure control means that controls fixing pressure at the nip part of the fixing device 20; and density adjustment means that adjusts an image density of an image to be formed according to the fixing pressure of the fixing device 20.SELECTED DRAWING: Figure 4 【課題】定着圧を可変制御する定着装置を備える画像形成装置において、定着不良を抑制する。【解決手段】定着ローラ２１と加圧ローラ２２との間に形成されるニップ部にトナー像Ｔを担持した記録媒体Ｐを搬送して、トナー像Ｔを記録媒体Ｐに定着する定着装置２０と、定着装置２０のニップ部での定着圧を制御する定着圧制御手段と、定着装置２０の定着圧に応じて、形成する画像の画像濃度を調整する濃度調整手段と、を備える。【選択図】図４
