Abstract:
A charging member has a surface layer. The surface layer contains a polysiloxane having a first unit, a second unit and a third unit each of which is represented by a specific formula. The ratio of the sum of the mole numbers of the first and second units to the sum of the mole numbers of the first to third units is in a specific range.
