Summary:PROBLEM TO BE SOLVED: To provide a magnet block advantageous of preventing the occurrence of rear-end void in an image obtained by a development process. SOLUTION: Upon magnetizing an accommodation groove 32a formed in the peripheral part of a magnet roller 32, which corresponds to the developing pole P1 of the magnet roller 40, the width-direction middle section of the bottom face 32b of the accommodation groove 32a is magnetized at higher degree than both its ends.
