The present invention is an image-forming method in which, when θ(A) is the contact angle relative to water of a surface of a photosensitive member and θ(B) is the contact angle relative to water of a surface of an intermediate transfer member, θ(B) is from 100° to 150°; θ(A) and θ(B) satisfy −70°≦θ(A)-θ(B)<0°; the toner has a toner particle that contains a binder resin; and the contact angle relative to water of a surface of a pellet molding of the toner is from 60° to 80°.

1. Field of the Invention
The present invention relates to an image-forming method used in, for example, electrophotographic apparatuses, electrostatic recording apparatuses, and electrostatic printing apparatuses.
2. Description of the Related Art
FIG. 1 is a diagram of a heat-sphering treatment apparatus used in the present invention;
FIG. 2 is a schematic diagram that shows an example of an electrophotographic apparatus of the present invention;
FIG. 3 is a schematic cross-sectional diagram in the thickness direction of the intermediate transfer member according to the present invention; and
The image-forming method of the present invention has a charging step of charging a surface of a photosensitive member; an electrostatic latent image-forming step of forming an electrostatic latent image on the surface of the charged photosensitive member; a developing step of developing the electrostatic latent image with a toner to form a toner image; a primary transfer step of transferring the toner image to a surface of an intermediate transfer member; a cleaning step of removing a residual toner that remains on the surface of the photosensitive member after the primary transfer step; a secondary transfer step of transferring to a transfer material the toner image that has been transferred to the surface of the intermediate transfer member; and a fixing step of fixing to the transfer material the toner image that has been transferred to the transfer material, wherein when θ(A) is the contact angle relative to water of the surface of the photosensitive member and θ(B) is the contact angle relative to water of the surface of the intermediate transfer member, θ(B) is from 100° to 150° and θ(A) and θ(B) satisfy the relationship in the following formula (1);
−70°≦θ(A)-θ(B)<0° (1)
the toner has a toner particle that contains a binder resin; and the contact angle relative to water of a surface of a pellet molding of the toner is from 60° to 80°.
