Claim One:
1. An image carrier comprising: a conductive base material; and a photosensitive layer formed on the base material, wherein the photosensitive layer includes an undercoat layer formed on the base material, a charge-generating layer formed on the undercoat layer, and a charge-transporting layer which is formed on the charge-generating layer and which is an outermost surface layer, the charge-transporting layer contains aggregate particles of a fluorine resin in an amount of 4.5% or more and 7.5% or less by weight, each particle of the aggregate particles having a number-averaged particle sphericality represented by Formula (1) of 0.62 or more and 0.7 or less: sphericality=4πA/L 2 (1), where π represents the circular constant, A represents a projection area of each particle of the aggregate particles, and L represents a peripheral length of a projected image of each particle of the aggregate particles, and the charge-transporting layer has a surface having a center-line average roughness (Ra) of 0.1 μm or more and 0.5 μm or less.
