A charging device is detachably attachable with respect to a body of an image forming apparatus. The charging device includes a charging roller and a cleaning member. The charging roller charges an image bearer. The cleaning member cleans the charging roller. The cleaning member has a higher cleaning performance on the charging roller during detachment in which the charging device is detached from the body of the image forming apparatus than during attachment in which the charging device is attached to the body of the image forming apparatus.
