Abstract
Official abstract text for this publication.
Disclosed is an image forming method including: developing, with an electrostatic charge image developing toner, a latent image formed on a photoreceptor in which a photosensitive layer is formed on a support containing aluminum as a main component; transferring a toner image on the photoreceptor onto a transfer target; and rubbing and removing the electrostatic charge image developing toner remaining on the photoreceptor after the transferring. The support contains silicon in a range of more than 0.6% by mass and 12.6% by mass or less, a shape factor of toner particles included in the electrostatic charge image developing toner is in a range of 0.800 to 0.970, and a content of the toner particles having a particle diameter of 2 μm or less is in a range of 5% by number to 30% by number.
First claim
Opening claim text (preview).
What is claimed is: 1. An image forming method comprising: developing, with an electrostatic charge image developing toner, a latent image formed on a photoreceptor in which a photosensitive layer is formed on a support containing aluminum as a main component; transferring a toner image on the photoreceptor onto a transfer target; and rubbing and removing the electrostatic charge image developing toner remaining on the photoreceptor after the transferring, wherein the support contains silicon in a range of more than 0.6% by mass and 12.6% by mass or less, a shape factor of toner particles included in the electrostatic charge image developing toner is in a range of 0.800 to 0.970, and a content of the toner particles having a particle diameter of 2 μm or less is in a range of 5% by number to 30% by number. 2. The image forming method according to claim 1 , wherein the shape factor of the toner particles is in a range of 0.930 to 0.970. 3. The image forming method according to claim 1 , wherein the toner particles contain strontium titanate. 4. The image forming method according to claim 1 , wherein the support contains silicon in a range of 0.8% by mass to 12.6% by mass. 5. The image forming method according to claim 1 , wherein the support contains silicon in a range of 1.3% by mass to 12.6% by mass. 6. The image forming method according to claim 1 , wherein the support contains silicon in a range of 1.3% by mass to 2.0% by mass. 7. An image forming system comprising: a photoreceptor in which a photosensitive layer is formed on a support containing aluminum as a main component; a developer that develops, with an electrostatic charge image developing toner, a latent image formed on the photoreceptor; a transferer that transfers a toner image on the photoreceptor onto a transfer target; and a cleaner that rubs and removes the electrostatic charge image developing toner remaining on the photoreceptor after transferring; and an electrostatic charge image developing toner, wherein the support contains silicon in a range of more than 0.6% by mass and 12.6% by mass or less, a shape factor of toner particles included in the electrostatic charge image developing toner is in a range of 0.800 to 0.970, and a content of the toner particles having a particle diameter of 2 μm or less is in a range of 5% by number to 30% by number.
