A toner-guiding sheet for guiding toner removed from an image carrying member. The sheet includes a free end portion for contacting a surface of the image carrying member, and a fixed portion, fixable on a fixing member, for fixing the toner-guiding sheet in a state in which the free end portion contacts the surface of the image carrying member. The toner-guiding sheet includes a film having a creep-deformation resisting property such that, when the film, fixed on the fixing member so that a distance &bgr; from a central portion in a longitudinal direction of the fixed portion of the sheet to a central portion in a longitudinal direction of the free end portion of the sheet is substantially 3.86 mm, is brought in contact with a surface of a contact member under conditions such that a distance &agr; from the central portion in the longitudinal direction of the fixed portion of the sheet to a central portion in the longitudinal direction of a contact portion of the free end portion on the surface of the contact member is substantially 1.86 mm, an amount of penetration &dgr; of the central portion in the longitudinal direction of the contact portion of the sheet with respect to the contact member is substantially 2.0 mm, and an amount of charge &xgr; of the central portion in the longitudinal direction of the contact portion of the sheet with respect to the contact member is substantially 0.74 mm, a change in the amount of penetration &dgr; when leaving the toner-guiding sheet in an environment of a temperature of substantially 45° C./a humidity of substantially 60% RH for substantially 30 days is equal to or less than substantially 0.43 mm.
