PROBLEM TO BE SOLVED: To provide a roller device having a roller holding side plate which holds a roller member via a bearing, to prevent the roller member from being displaced when in drive, an imaging apparatus as the roller device, a process cartridge including the imaging apparatus, and an image forming apparatus.SOLUTION: An image forming unit 20 includes: a developing roller 3; and a pair of gap faceplates 207 for holding the developing roller 3 so as to be rotatable, via a faceplate development bearing 208. Relative positions of a paratype stud 241 of a developing case side plate 240 of a developing apparatus 2 arranged inside the gap faceplate 207 and a faceplate paratype hole 270a of the gap faceplate 207 are fixed by a pressure screw 210 in an axially orthogonal direction. The pressure screw 210 is tightened to bend the gap faceplate 270. |
