1. An image forming method comprising:
(1) charging the surface of an electrophotographic photosensitive member;
(2) forming an electrostatic latent image by exposing the charged surface of the electrophotographic photosensitive member;
(3) forming a toner image on the surface of the electrophotographic photosensitive member by developing the electrostatic latent image with a toner,
(4) transferring the toner image to a transfer material through or without an intermediate transfer body;
(5) removing the transfer residual toner from the surface of the electrophotographic photosensitive member after the toner image is transferred, and (6) irradiating the surface of the electrophotographic photosensitive member, from which the transfer residual toner has been removed, with destaticizing light for eliminating residual charge on the surface of the electrophotographic photosensitive member,
wherein a surface layer of the electrophotographic photosensitive member contains a compound having a structure represented by formula (1) below in an amount of 0.1% to 10% by mass based on the total mass of the surface layer, and when in a charged region of the surface of the electrophotographic photosensitive member charged in the step (1), a charged region in which the electrostatic latent image is formed in the step (2) is referred to as an “image forming region” and a charged region in which the electrostatic latent image is not formed is referred to as a “non-image forming region”, the non-image forming region is not irradiated with the destaticizing light or is irradiated with the reduced destaticizing light in the step (6),
