Abstract
A developing device includes a first rotatable member having a rotation center Q and a second rotatable member having a rotation center R. When a rectilinear line connecting the rotation center Q and an intersection point X is a rectilinear line L, a rectilinear line connecting the rotation center Q and a magnetic flux density peak position Y is a rectilinear line L, a rectilinear line connecting the rotation center Q and a magnetic flux density peak position Z is a rectilinear line L, an acute angle formed between the rectilinear line Land the rectilinear line Lis α [°], and an acute angle formed between the rectilinear line Land the rectilinear line Lis β [°], α>β is satisfied.
