′尚が低下する。When conventional electrophotographic transfer paper using a negative polarity toner development method is used in such an electrophotographic copying machine using a positive polarity toner development method, the amount of paper attached to the photoconductor during the toe image transfer process is sufficiently reduced. If this toner is not cleaned or the cleaned toner is reused, the toner particles may be mixed into the developer, causing punk and ground fog, resulting in poor copy quality.

To prevent this, reduce the moisture content of the paper to 4.5 to 5.
5% and wrapped in moisture-proof wrapping paper to prevent moisture absorption and desorption during storage.

に基づいて本発明を完成した。The inventors of the present invention have determined that the cause of this problem is due to the negative common practice, and found that the paper dust component of conventional electrophotographic transfer paper becomes electrically charged on the shell due to friction, welding, separation, etc. with toner or carrier. ,
It was discovered that the reason for the formation of aggregates of paper powder and toner was that the toner of opposite polarity was responsible for the inhalation of the lungs, and based on this knowledge, the present invention was completed.

ランドの汚れやコピー画像に細かい抜けを発生させる。In other words, in the 41 toner image transfer process of conventional transfer paper, paper dust is generated on the front surface and cut surface of the transfer paper that adheres to the photoreceptor, mainly filler powder such as talc and kaolin, and some fine fibers. If the toner is not cleaned, the toner may be mixed into the developer when the toner is reused after cleaning. The mixed mixture charges the shellfish due to friction, contact, and separation with the toner and carrier, resulting in the formation of aggregates (generally weakly opposite polarity) with positive polarity toner, or reverse polarity. This increases the amount of dirt, causing stains on the pack ground and small holes in the copied image.

。In order to prevent this, it has become clear through various methods that the amount of paper dust adhering to the photoreceptor of a copying machine during toner image transfer can be reduced to zero or significantly.

The ratio of hardwood bleached kraft (ξrupu) and NBKP (softwood bleached kraft no. Starch (sometimes polyvinyl alcohol may be mixed in) is 1 to 3 f/
m2 is applied. Moreover, no measures have been taken to reduce the amount of paper dust + 1 deposited on the photoreceptor during toner image transfer in Shigeko's photographic machine. Paper dust that affects transfer is generated from both the cut surface and the surface of the transfer paper, with a ratio of 10:1 to 8, and generally comes from the cut surface. Paper dust from the cutting surface is removed from adhesion of cellulose fibers themselves, cellulose, fillers, and starch when paper is cut from a roll using an automatic small cutting machine (LENOX or WILL) or when a large sheet is cut using a guillotine cutting machine. These are fibers, fillers, and/or starches that have been cut off and released. When the cut surface of the transfer paper was experimentally hardened with resin and the amount of paper dust generated from the cut surface was reduced by Ot/, the amount of paper dust adhering to the photoreceptor during transfer was 10% of the conventional amount.

。However, paper is made in a neutral system with a pH of 7 or higher (JISP-81
33), the surface strength was stronger compared to paper made in an acidic system and had a pH of less than 7, and no paper dust was observed. This is thought to be due to the fact that in the neutral range of pH 7 or higher, the swelling properties of the fibers are good and the fiber bonding becomes strong.
