Abstract
The electroconductive member has an electroconductive support and a surface layer formed on the electroconductive support, wherein the surface layer has a porous body having a continuous open pore, and the electroconductive member satisfies the following (1) and (2):(1) in a specific condition, a surface potential of the electroconductive member, after an elapse of 10 seconds since a completion of a discharge is 10 V or more; and(2) when applying a direct voltage between a polyethylene terephthalate film as a member to be charged and the electroconductive member, and charging the polyethylene terephthalate film, |Vd|≧|Vin|−|Vth| is satisfied within a range of |Vin|>|Vth|, wherein, Vd represents a charge potential of the polyethylene terephthalate film, Vin represents a voltage applied between the electroconductive member and the polyethylene terephthalate film, Vth represents a discharge starting voltage.
