Abstract
Provided is a charging member in which the hardness of its surface is increased while surface free energy is kept low, the surface is hard to scratch even in long-term use, and a toner or the like is hard to adhere to the surface. The charging member according to the present invention includes a conductive support, a conductive elastic layer, and a surface region containing a cured material of a compound represented by the following formula (1):wherein n represents an integer of 0-6, m represents an integer of 0-6, the total of n and m is from 2 to 6, x and y each independently represent an integer of 0-4, and R1 and R2 each independently represent a hydrogen atom or a methyl group.
