A charging device for charging a movable object to be charged, has a charging member which contacts with the object to be charged, and a power source for applying a voltage to the charging member, wherein the power spectrum PS satisfies the following relation when the space frequency of the profile of the surface of the charging member is analyzed. In the section of 10 </= f </= 100 (cycles/mm): PS </= -2.5 x log (f/2) ( mu m<2>> The invention therefore presents a charging device capable of preventing charge unevenness due to undulations on the surface of the charging member, and charging uniformly, and generating very little ozone. <IMAGE> |
