    摘要： A degradation level estimating device for estimating degradation level of a photoreceptor of an image forming apparatus performing at least a charging process, an optical image writing process, a developing process, and a transferring process in which a toner image on the photoreceptor is transferred onto a receiver while applying a charge to the photoreceptor. The degradation level estimating device includes a charge dependence detector to detect charge quantity dependence of a charge property of the photoreceptor in the charging process on the quantity of the charge applied to the photoreceptor in the last transferring process by subjecting the photoreceptor to the processes plural times without performing the optical image writing process, followed by the charging process, while changing the quantity of the charge and measuring the charge property of the photoreceptor. The degradation level estimating device estimates the degradation level of the photoreceptor based on the charge quantity dependence.

    摘要： A photoconductor includes an electroconductive substrate; an undercoat layer overlying the electroconductive substrate; and a photosensitive layer overlying the undercoat layer. The undercoat layer includes a urethane resin, a metal oxide particle and a compound having the following formula (1): wherein R1 to R8 independently represent a hydrogen atom, a nitro group, a cyano group, a halogen atom, a hydroxyl group, a saturated or an unsaturated aliphatic hydrocarbon group optionally having a substituent, an aromatic hydrocarbon group optionally having a substituent, an alkoxy group optionally having a substituent, an aryloxy group optionally having a substituent, a sulfo group optionally having a substituent, an amino group, a dialkylamino group optionally having a substituent or an diarylamino group optionally having a substituent; and R3 and R4, R4 and R5, R6 and R7, and R7 and R8 may be bonded with each other to form an aromatic ring.
