摘要： The present invention relates to a process for manufacturing a new elastomer having high elasticity, mechanical strength and processability from epoxy compounds, trimellitoyl-functional polymers and a third element. The third element is any of acid anhydride compounds having a molecular weight lower than 700, and having at least one acid anhydride group, such as maleic, phthalic, succinic, adipic, trimellitic, pyromellitic, and benzophenone tetracarboxylic anhydrides. It is, according to another aspect, an improvement of physical properties, especially tensile and tear strengths of the elastomer manufactured by reacting said first two elements according to the copending application Ser. No. 143,643, filed May 14, 1971, while keeping desirably low exothermicity and thermal contraction during the curing.

摘要： An image forming apparatus includes a fixing device. The fixing device includes a rotatable endless fixing member, a nip forming member arranged inside the fixing member, a pressing member in contact with the nip forming member via the fixing member, and a heating source configured to heat the fixing member. When an abnormality occurs in at least one of the fixing device and other devices included in the image forming apparatus, a rotation of the fixing member is stopped prior to stopping a rotation driving of a discharging unit and, after stopping, the fixing member is controlled to rotate.

摘要： A fixing device includes a fixing rotary body rotatable in a given direction of rotation and a heater disposed opposite the fixing rotary body to heat the fixing rotary body. A pressing rotary body contacts the fixing rotary body to form a fixing nip therebetween through which a recording medium is conveyed. A separator is disposed downstream from the fixing nip in a recording medium conveyance direction to separate the recording medium from one of the fixing rotary body and the pressing rotary body. The separator includes a separation plate including an upstream portion disposed opposite the fixing nip and at least one slot disposed downstream from the upstream portion in the recording medium conveyance direction.
