Claim Text:
1. In the context of an electrophotographic image-forming device which employs toner, an electrophotographic image-forming device having an end seal member characterized in that it has a toner carrier having toner, and an end seal member for preventing leakage of toner from an end of a toner carrier comprising a rectangular sealing member having a step comprising a projecting region and a recessed region forming a stripe in the form of a band of linear configuration, said sealing member having a toner scraping angle and a contact surface which contacts a surface of a toner carrier and a projecting region and a recessed region, the foregoing recessed region being made to bend in a direction of a toner carrier due to bending load from contact pressure between an end seal member and a toner carrier, and having action whereby entry of toner into a sealing member is controlled and action whereby toner is scraped and action whereby toner is transferred, a control angle being formed in a linear direction from a projecting region and a recessed region at a stripe in the form of a band at a surface of a sealing member for return of toner to a toner storage container or a temporary toner storage container and for prevention of leakage of toner to an exterior from a toner carrier due to surface velocity of a toner carrier, an end seal member being provided with a recessed region and an edge of a projecting region for preventing leakage of toner from a toner carrier, said sealing member being employed at an end seal member of a toner carrier in an image-forming device, wherein the contact surface of the toner carrier contacts directly with the contact surface of the sealing member.
