定着することにより複写物が得られる。(Prior Art) In image forming apparatuses that use electrophotography or electrostatic printing, an electrostatic latent image formed on an image carrier is generally developed using a dry developer (toner), and the image is transferred in the transfer process. , Transfer paper is stacked on an image carrier, the transfer paper is charged with a corona discharger, the developed toner image is transferred to the transfer paper, and the toner on the transfer paper is then fixed by heat or pressure. A copy is obtained.

為、紙に薄層で樹脂コートを行う事により上記問題点を
防止していた。一方、従来定着工程時において、転写紙
が加熱によって脱湿するために、カールが発生し、しわ
より等の問題点があった。In the conventional transfer process, transfer paper that has absorbed water causes transfer defects, resulting in problems such as image unevenness and poor density. For this reason, the above-mentioned problems have been prevented by coating paper with a thin layer of resin. On the other hand, in the conventional fixing process, the transfer paper is dehumidified by heating, which causes curling and wrinkles.
そこで、上記問題点を解消するために、定着ローラの形

ールやしわより等の発生を防止している。Therefore, in order to solve the above problem, by forming the fixing rollers so that one side has a crown shape and the other side has an inverted crown shape, the transfer paper is transported when the transfer paper passes between the fixing rollers. Both ends of the leading edge are pulled to prevent curls, wrinkles, etc.

いう欠点があった。(Problems to be Solved by the Invention) However, resin coating on paper significantly impairs writability and loses the characteristics of PPC. Furthermore, when the transfer paper is pulled as described above, the paper itself is deformed by the heat and pressure of the fixing roller, and as a result, there is a drawback that an image faithful to the original cannot be reproduced.
これは、ＡＯやＡ２等の広幅紙用の複写機や高速機にお

Therefore, the transfer paper containing the porous polyester particles has excellent water resistance and heat resistance, and can prevent transfer defects during transfer and deformation due to heat and pressure during fixing, and faithfully reproduce the original. becomes possible. In addition, by using the vesicles in the porous polyester particles that further contain a fragrance, we can also produce L-sized medium-sized 7 paper sheets that have a natural scent that eliminates the odor of the toner after fixing. Can be provided.

の剛性が大きすぎ搬送不良や定着不良を発生する。The amount of the porous polyester powder added is generally 0.1 to 20%, particularly preferably 5 to 15%, based on the weight of the base paper. When the amount added is less than the above range, the effects of the present invention cannot be obtained and poor transfer, curling, wrinkles, etc. occur. Furthermore, if the amount added is greater than the above range, the rigidity of the paper will be too large, leading to poor conveyance and poor fixing.
