Abstract
An image forming method, comprising steps of: forming a toner image on an organic electrophotographic photoreceptor having a siloxane based resin layer as a protective layer with a developer carried on a developing sleeve, wherein a distance Dsd (μm) between the organic electrophotographic photoreceptor and the developing sleeve and a thickness t (μm) of the protective layer of the organic electrophotographic photoreceptor satisfy formula (1): 35t+400<Dsd (1)

An image forming method, comprising steps of:
- forming a toner image on an organic electrophotographic photoreceptor having a siloxane based resin layer as a protective layer,
- wherein a distance Dsd (μm) between the organic electrophotographic photoreceptor and the developing sleeve and a thickness t (μm) of the protective layer of the organic electrophotographic photoreceptor satisfy formula (1):
- 35t+400<Dsd (1);
- and
- wherein Dsd is between 350 and 800 μm.
An image forming method, comprising steps of:
- charging an organic electrophotographic photoreceptor having a siloxane based resin layer as a protective layer;
- exposing digital image on the charged photoreceptor by a digital image exposing method so as to form a latent image;
- and
- developing the latent image with a developer carried on a developing sleeve so as to form a toner image;
- wherein a distance Dsd (μm) between the organic electrophotographic photoreceptor and the developing sleeve, a thickness t (μm) of the protective layer of the organic electrophotographic photoreceptor and a difference ΔV (V) between a voltage (V) applied onto the developing sleeve and an electric potential (V) of an exposed portion of the organic electrophotographic photoreceptor satisfy formula (2):
- |(35t+400)×ΔV|/500<Dsd (2);
- and
- wherein Dsd is between 350 and 800 μm.
An image forming apparatus, comprising
- an organic electrophotographic photoreceptor having a siloxane based resin layer as a protective layer;
- a charging device to charge the organic electrophotographic photoreceptor;

- and
- a developing device to develop the latent image so as to form a toner image,
- wherein a distance Dsd (μm) between the organic electrophotographic photoreceptor and the developing sleeve and a thickness t (μm) of the protective layer of the organic electrophotographic photoreceptor satisfy formula (1):
- 35t+400<Dsd (1);
- and
- wherein Dsd is between 350 and 800 μm.
