Abstract:
A charging device includes: a charging component, and a cleaning member for the charging component, containing a substrate and an elastic layer that contains a silicone oil and is arranged in a spiral form on an outer surface of the substrate, the charging device being satisfying a following formula: A≦6 atomic % wherein A is a maximum value of the contents of Si atom constituting a siloxane skeleton with respect to total atoms at a contact part where the charging component is brought into contact with the elastic layer and at a non-contact part where the charging component is not brought into contact with the elastic layer, in which the contents of Si atom are obtained by X-ray photoelectron spectroscopy of a surface of the charging component after preparing the elastic layer of the cleaning member for the charging component in an initial state and the charging component in an initial state to bring into contact with each other for 24 hours.
