Abstract:
A method of forming an image, comprisinga developing step of forming a toner image by developing an electrostatic latent image formed on a latent image holding member by a developer containing a toner; a transferring step of transferring the toner image formed on the latent image holding member onto a transfer material; and a fusing step of fusing the toner image transferred on the transfer material, wherein the toner comprises at least a colorant and a binder resin in which a principal component is a crystalline resin; and the fusing step is performed by a fusing apparatus comprising a heat-fixing roll and an endless belt, the heat-fixing roll comprising a cylindrical core metal coated with a heat resistant elastic body layer and a heat resistant resin layer in this order and the endless belt having a pressure member inside, forms a nip by winding the endless belt round the heat-fixing roll at a predetermined angle thereby allowing a recording sheet to pass through between the endless belt and the heat-fixing roll, and generates strain on the heat resistant elastic body layer of the heat-fixing roll by urging the pressure member against the heat-fixing roll via the endless belt in the nip.
