    摘要: A pressure device applies pressure to a sheet medium on part of a surface of which an image bearer is formed. The pressure device includes: a driving unit that changes a distance between a first pressing unit and a second pressing unit; a control unit that controls the driving unit such that the distance between the first pressing unit and the second pressing unit becomes a set target value; and a target setting unit that sets the target value to a first distance that is larger than a thickness of the sheet medium when the sheet medium is not present between the first pressing unit and the second pressing unit, and sets the target value to a second distance for applying a target pressure to the sheet medium when the sheet medium and the image bearer are present between the first pressing unit and the second pressing unit.

    摘要: In a transport device, a first speed control unit controls a rotating speed of a first roller driving unit to reach a first target speed, and a second speed control unit controls a rotating speed of a second roller driving unit to reach a second target speed. The second speed control unit is arranged to perform, when a print medium is transported by both a first transport roller unit and a second transport roller unit, a follower control having a response sensibility to speed fluctuations in a predetermined frequency region of a control system, which is smaller than a response sensibility when the print medium is transported by the second transport roller unit solely.
