Dear Masahiro,
I'm not quite sure what analysis you are doing, but I will give it a go.
Let's take your original images, A and B.
You coregister B to A. You now have B.mat which specifies the coregistration.
In the same step or later you reslice B to be in the same voxel space as A,
giving rB.img.
You then do some further processing of rB.img outside SPM.
To reslice rB.img to the voxel space of B.img, you can merely choose realign or
coregister, reslice only, and choose B followed by rB, as the B.mat information
gives the coregistration between A and B (as well as between B and A).
Best,
Matthew
