Abstract: A winding member winds a seal member that seals an opening of a developer storage unit. The winding member includes a first holding portion having a first engaging portion, and a second holding portion having a second engaging portion to be engaged with the first engaging portion, configured to hold the sealing member between the first and second holding portions, wherein an end of the first holding portion and an end of the second holding portion are connected, so that the first holding portion and the second holding portion are relatively movable, and wherein the first engaging portion is engaged with the second engaging portion while the sealing member is held between the first holding portion and the second holding portion.

Abstract: A process cartridge attachable to and detachable from an electrophotographic image forming apparatus includes a first unit having an electrophotographic photosensitive member, and a second unit including a developing roller configured to develop a latent image formed on the electrophotographic photosensitive member, and a sheet member which is disposed along the developing roller in a lengthwise direction of the developing roller and contacts the electrophotographic photosensitive member to restrain scattering of developer, wherein a contact portion of the sheet member that contacts the electrophotographic photosensitive member is roughened by a roughening process.

Abstract: A method of fixing a flavorant for improving the small of a sidestream smoke of tobacco. This method includes applying, to tobacco wrapper paper, a tobacco sidestream smoke smell-improving agent including an ethanol or propylene glycol solution of the flavorant added to an emulsion of an ethylene-vinyl acetate copolymer having an ethylene content of 30% by weight or less, the emulsion having a solid content of 10 to 60% by weight, and drying it to fix the flavorant to the wrapper paper. The ethanol solution of the flavorant is added to the emulsion such that an amount of ethanol is 40% by weight or less with respect to 100% by weight of the emulsion, while the propylene glycol of the flavorant is added to the emulsion such that an amount of propylene glycol is 11% by weight or less with respect to 100% by weight of the emulsion.

Abstract: A cigarette paper having a sidestream smoke smell-improving agent including a lactone in its free state, or a salt of a hydroxy acid corresponding to the lactone, as well as a cigarette wrapped by the cigarette paper. The salt of the hydroxy acid can be an alkali metal salt or an alkaline earth metal salt. The lactone can be a lactone having five or more ring members. The lactone can be a &ggr;-lactone or a &dgr;-lactone.
