A correcting unit moves a second end of a first roller from among the rollers in either one of a forward direction and a backward direction while fixing its first end based on a result of detecting the displacement of the belt member such that a tilt of a rotating shaft of the first roller is changed to correct a meandering of the belt member. An adjusting unit adjusts a fixing position of the first end.

摘要： A cooling device includes a cooling member to cool a recording material. The cooling member includes a cooling surface member, a heat exchanging member, and a fastening member. The cooling surface member has a cooling surface to directly or indirectly contact the recording material and absorb heat of the recording material to cool the recording material. The heat exchanging member is directly or indirectly joined to the cooling surface member to radiate heat absorbed by the cooling surface member directly or indirectly via a radiation member. The fastening member fastens the cooling surface member and the heat exchanging member to retain a joined state in which the cooling surface member and the heat exchanging member are directly or indirectly joined to each other. The cooling surface member and the heat exchanging member are separable from the joined state to a separated state without damaging the fastening member.

摘要： In a belt device, a first detecting unit detects a widthwise displacement of a belt, and a correcting unit corrects displacement of the belt in the width direction during a period starting from turning power on and ending with completion of drive preparation of the belt based on the widthwise displacement. Moreover, a second detecting unit detects whether the belt has displaced in the width direction by an amount that is greater than a threshold, and a belt stopping unit stops running of the belt when the second detecting unit detects that the belt has displaced by an amount that is greater than the threshold.

摘要： A transfer device includes a rotatable image bearer configured to bear a toner image to be transferred to a recording medium, a first rotator, and a second rotator. The second rotator is configured to contact the first rotator via the rotatable image bearer to form a transfer nip in which the recording medium is sandwiched. The second rotator is rotatable with the image bearer. The transfer device satisfies a conditional expression (t1+R)/(t2+R)>0.98, where t1 represents a thickness of a thinnest recording medium, t2 represents a thickness of a thickest recording medium, and R represents a radius of curvature of the transfer nip.
