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.

Image forming method and image forming system

An image forming method includes: supplying a powder onto a recording medium; supplying a coated toner onto the powder on the recording medium; and fixing the powder to the recording medium by heating the coated toner supplied onto the powder and melting the coated toner.

Image forming method and image forming device

According to an image forming apparatus and an image forming method of the present invention, an image is formed by arranging powderson a surface of a resin image composed of sheet S and a color toner layer (resin layer) arranged thereon. The image forming apparatus includes: a powder spraying sectionfor supplying powderson the surface of resin layerwhich is adjusted to be in a softened state; and rubbing rollerfor rubbing, from a side of resin layer, the resin image to which powdershave been supplied.

Image forming apparatus and image forming method

An image forming apparatus for forming an image by arranging powder on a surface of a layer of a resin image formed of a recording medium and a thermoplastic resin layer arranged thereon, includes: a powder supplying device that supplies the powder to the surface of the layer of the resin image; a hardware processor that sets a rubbing condition of the resin image in accordance with an image to be formed; and a rubbing device that rubs the resin image, which is adjusted to a temperature at which the layer of the resin image is softened or higher to which the powder is supplied from a side of the layer of the resin image according to the set rubbing condition.

Image forming apparatus with a powder supplying device and an image forming method supplying powder to a resin image

A high quality image excellent in low-temperature fixability and good in color stability can be formed by an image forming method of the present invention. In the image forming method, an image is formed by an electrophotographic method using toners of plural colors. Each of the toners of the plural colors contains a crystalline resin, methanol concentrations (%) at transmittance of 50% obtained for methanol wettability evaluation of the toners of the plural colors all fall in a range of 15 to 60%, and assuming that a maximum value and a minimum value of the methanol concentrations (%) at transmittance of 50% obtained for the methanol wettability evaluation of the toners of the plural colors are respectively WH (%) and WL (%), a relationship of 4&#x2264;WH&#x2212;WL&#x2264;30 is satisfied.

Image forming method

Provided is a means that can improve performance such as high-speed fixability and fixable temperature range while securing low temperature fixability, in an electrostatic charge image developing toner concurrently using a crystalline resin and an amorphous resin as binder resins constituting toner base particles. An electrostatic charge image developing toner containing toner base particles containing an amorphous resin and a crystalline resin is constituted such that lamellar crystal structures and fibrous crystal structures are dispersed in the cross section of the toner base particles.
