Abstract:
An image forming apparatus includes a photoconductor and an electricity removing member electrically grounded and disposed to be in contact with a surface of the photoconductor. In the image forming apparatus, with regard to a capacitance component of an inner impedance of the electricity removing member and a capacitance 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 capacitance component of the contact impedance by the capacitance component of the inner impedance is equal to or lower than a predetermined first specific value, and the capacitance component of the inner impedance is equal to or lower than a predetermined second specific value.
