Abstract:
In an image forming apparatus, a resistance component of an inner impedance of an electricity removing member is equal to or lower than a value that is obtained by multiplying a calculated resistance value by a first 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 a photoconductor to a predetermined post-electricity-removal potential during an electricity removal time, the first specific value being calculated based on a ratio of a linear speed of the electricity removing member to a linear speed of the photoconductor, and a resistance component of the contact impedance of the electricity removing member is equal to or lower than a value that is obtained by multiplying the calculated resistance value by a second specific value that is calculated based on the ratio.
