PROBLEM TO BE SOLVED: To provide bearing devices using small bearings for supporting a pair of rollers such as a fixing roller and a pressure roller of a fixing device, to be thrust in the direction of approaching each other. SOLUTION: The bearing devices 22A, 22B comprises at least one of pairs of bearings 26A-26D whose outer peripheral faces abut on the outer peripheral face of a rotating shaft 12a of the fixing roller 11A or the pressure roller 11B. The bearings 26A-26D perpendicular to a line L1 connecting the axes of the fixing roller 11A and the pressure roller 11B to each other are arranged outside a region held between mutually parallel lines L2, L3 passing through the axes. Pairs of arms 37A-37D having the bearings 26A-26D at the front ends are connected to one another at their base ends with a connection mechanism 38 in the condition that their rotating angle positions are adjustable.
