Electrophotographic image forming apparatus and electricity removing member used in the same

An image forming apparatus comprising:

• a photoconductor;
• and
• an electricity removing member electrically grounded and disposed to be in contact with a surface of the photoconductor, wherein
• with regard to a resistance component of an inner impedance of the electricity removing member and a resistance component of a contact impedance of the electricity removing member that are calculated from a Cole-Cole plot obtained from measurement by an AC impedance method in a predetermined frequency range,
• a value obtained by dividing the resistance component of the contact impedance by the resistance component of the inner impedance is equal to or lower than a predetermined third specific value, and
• the resistance component of the inner impedance is equal to or lower than a value obtained by multiplying a calculated resistance value by a predetermined fourth specific value, the calculated resistance value being calculated, based on a predetermined formula, as a DC resistance value of the electricity removing member that is required to reduce a pre-electricity-removal potential of the photoconductor to a post-electricity-removal potential in an electricity removal time that is obtained by dividing a contact width of the photoconductor and the electricity removing member by a linear speed of the photoconductor.
