Abstract
An image forming method forms an image by performing charging, exposing, developing, and transferring in a rotation direction of a rotationally driven photoreceptor, wherein the charging is performed by a roller charging method, exposing a surface of the photoreceptor to light and eliminating charges on the surface of the photoreceptor are included between the developing and the transferring, the photoreceptor includes at least a charge transporting layer and a protective layer laminated on the charge transporting layer on a conductive support, and energy of light for irradiation in the exposing the surface of the photoreceptor to light is in a range of 0.0001 to 500 μW/mm2 on the surface of the photoreceptor.
Claims6
An image forming method that forms an image by performing charging, exposing, developing, and transferring in a rotation direction of a rotationally driven photoreceptor, wherein
- the charging is performed by a roller charging method,
- exposing a surface of the photoreceptor to light and eliminating charges on the surface of the photoreceptor are included between the developing and the transferring,
- the photoreceptor includes at least a charge transporting layer and a protective layer laminated on the charge transporting layer on a conductive support,
- energy of light for irradiation in the exposing the surface of the photoreceptor to light is in a range of 0.0001 to 500 μW/mm2 on the surface of the photoreceptor,
- the protective layer contains a (meth)acrylic or polycarbonate resin and SnO2 or TiO2 inorganic fine particles,
- the inorganic fine particles have a number average primary particle diameter in a range of 5 to 500 nm, and
- a surface of the protective layer has a universal hardness in a range of 200 to 350 N/mm2.
An image forming device comprising:
- a charger;
- an exposer;
- a developer;
- and a transferer in a rotation direction of a rotationally driven photoreceptor, wherein
- the charger includes a charging roller,
- a pre-transfer charge eliminator that exposes a surface of the photoreceptor to light and eliminates charges on the surface of the photoreceptor is disposed between the developer and the transferer,
- the photoreceptor includes at least a charge transporting layer and a protective layer laminated on the charge transporting layer on a conductive support,
- energy of light for irradiation in the pre-transfer charge eliminator is in a range of 0.0001 to 500 μW/mm2 on the surface of the photoreceptor,
- the protective layer contains a (meth)acrylic or polycarbonate resin and SnO2 or TiO2 inorganic fine particles,
- the inorganic fine particles have a number average primary particle diameter in a range of 5 to 500 nm, and
- a surface of the protective layer has a universal hardness in a range of 200 to 350 N/mm2.
