PROBLEM TO BE SOLVED: To realize a developing device or the like having a seal structure that uniformizes pressing force of a layer thickness regulating member against a developer carrying roller, thereby hindering developer leak. SOLUTION: In the developing device having a pressing member 570 in which the layer thickness regulating member 560 having an abutting member 560a and a biasing member 560b is pressed against the developer carrying roller 510, both ends of the pressing member 570 in an axial direction of the developer carrying roller 510 are disposed further outside than both ends of the abutting member 560a.
