The invention provides an image forming method, comprising transferring a
toner image to an electrophotographic recording sheet, layering the
electrophotographic recording sheet on a fixing belt and heating and
pressing the sheet, and cooling the electrophotographic recording sheet
and separating the sheet from the fixing belt. The electrophotographic
recording sheet comprises a support comprising cellulose pulp-containing
base paper and a toner image-receiving layer comprising a thermoplastic
resin disposed on the support. A shrinkage percentage of the
electrophotographic recording sheet in a CD direction in the heating step
is 1.3% or less. The support preferably further comprises either a
polyolefin-containing layer or a coating that contains at least one
selected from the group consisting of kaolin, a pigment, a resin, a
rubber latex, or a polymer material and that is provided on one or both
surfaces of the base paper.
