Abstract: An image forming apparatus performs printing based on a print job and receives a completion notification from an automatic printed material delivery apparatus. Based on receipt of the completion notification, the image forming apparatus transmits a receipt acknowledgement request to a personal computer (PC) corresponding to a user (a requested user or a designated user) based on the job. Further, the image forming apparatus receives, from the PC, an acknowledgement notification based on a user operation performed on the PC in connection with the receipt acknowledgement request. In response to receipt of the acknowledgement notification, the image forming apparatus registers information indicating that the printed material has been received by the user based on the job as a job log of the job.

Abstract: Thermoplastic resin compositions which comprise 20-70 parts by weight of a polyvinyl chloride resin and 80-30 parts by weight of a mixed composition of the following copolymers (A) and (B) at the following ratio:(A) 90-50% by weight of a copolymer which comprises 65-90 parts by weight of .alpha.-methylstyrene with 35-10 parts by weight of acrylonitrile and 0-5 parts by weight of a copolymerizable vinyl monomer and contains 30 parts by weight or more of a component having an .alpha.-methylstyrene content of 82% by weight or higher; and(B) 10-50% by weight of a graft copolymer obtained by reacting 35-80% by weight of a conjugated diene rubber and 65-20% by weight of a monomer comprising a monovinyl aromatic compound, an unsaturated nitrile compound or an alkyl methacrylate.These compositions have greatly improved heat resistance, especially resistance to heat distortion, and impact resistance over those of polyvinyl chloride resins.
