Abstract:
An image forming apparatus includes an image holding member, a charging device that charges a surface of the image holding member and includes a charging member disposed in contact with the surface of the image holding member, an exposure device that forms a latent image by exposing the charged surface, a developing device that forms a toner image by developing the latent image with toner, and a transfer device that transfers the toner image formed to a recording medium. An amplitude Af with a period Lf (mm) satisfying the formula (F−5)≤(V/L)≤(F+5) is 0.80 μm or less where F is the natural frequency (Hz) of the exposure device, V is the rotational peripheral velocity (mm/s) of the charging member, and L is the period (mm) in analysis of the circumferential direction period of the surface shape of the charging member.

Claim (Index 3):
The image forming apparatus according to  claim 2 , wherein the amplitude Af is 0.35 \u03bcm or less.
