Title: Toner
Inventor: ICHIKAWA KAZUHIRO
IPC: G03G9/08
Filed: 2002-01-23
Abstract: PROBLEM TO BE SOLVED: To reduce the occurrence of filming by suppressing the separation of an additive from toner at the time of contact transfer. SOLUTION: As for the toner T, the inclination (the equivalent particle size of the additive/the equivalent particle size of base particle) θ of an approximate line α obtained by making the distribution of the equivalent particle size of the additive (SiO2 ) to the equivalent particle size of the base particle (C) approximate by a method of least squares is <=0.6, and the additive separated from the base particle is set to <=5% of the entire toner. Thus, the amount and the particle size of the additive (SiO2 ) adhering to the base particle (C) are restricted and the separation of the additive (SiO2 ) from the base particle (C) is reduced at a contact transfer stage by a latent image carrier and a transfer device in the midst of an image forming process.  Therefore, the retention of the additive (SiO2 ) at the cleaning part of the latent image carrier is restrained, and the filming is reduced.

Abstract: <P>PROBLEM TO BE SOLVED: To obtain an adhesive which has excellent shelf stability, and cures rapidly at a low temperature.  <P>SOLUTION: The adhesive has a first curing agent and a thermoset resin, but the resin causes no polymerization reaction on account of absence of a second curing agent and the adhesive has high shelf stability. When an adhesive layer 25 comprising the adhesive and a second curing agent layer 28 comprising the second curing agent are heat compressed in an adhesion state thereof, the first curing agent in the layer 25 reacts with the second curing agent in the layer 28 to polymerize the thermoset resin in the layer 25. When a metal chelate or a metal alcoholate, and a silane coupling agent are used as the first and second curing agents, respectively, a cation is caused by reacting the silane coupling agent with the metal chelate, thereby cation polymerizing the thermoset resin by the cation. Consequently, the adhesive is cured at a lower temperature and in a shorter time as compared with a convention method.  <P>COPYRIGHT: (C)2003,JPO
