Abstract: PROBLEM TO BE SOLVED: To suppress and minimize the production of odor and bacteria by carrying out a ventilation from a direction along corrugated grooves provided on an assembly of unit plates made of a material containing no water, whose surface is hydrophilic, and feeding water from the upper part of a humidifying unit. SOLUTION: A humidifying element E comprising an assembly of unit plates 50 and 60 is made of a material containing no water and its surface is hydrophilic. The humidifying unit is formed by combining together the unit plates 50 and 60 having many corrugated grooves so as to make the corrugated grooves intersect mutually. A ventilation is carried out from a direction along the corrugated grooves (an arrow M). Water is fed from the upper part of the humidifying unit (from a water feed tank 81). A water feeding capacity from the water feed tank 81 is designed to feed water of the amount of about three times an evaporation capacity to the humidifying element E during a humidifying operation. Thus, even when the same element E is used for a long time, troubles such as the production of its odor and bacteria can be suppressed and minimized.

Abstract: PURPOSE:To improve transfer efficiency, durability and productivity by using an intermediate transfer body where an elastic layer made of rubber whose viscosity before hardening is so high that it cannot pass through the texture of a base material is formed on the belt-like base material made of polyamide fiber fabric. CONSTITUTION:The intermediate transfer body 31 is formed by successively providing the elastic layer 33 made of the rubber whose viscosity before hardening is so high that it cannot pass through the texture of the base material 32 and a transfer layer 34 made of rubber whose viscosity before hardening is lower than that of the rubber of the layer 33 before hardening on the belt-like base material 32 made of the polyamide fiber fabric by means of coating, etc. After a toner image formed on an image holding body 1 is transferred to the belt-like intermediate transfer body 3 in a primary transfer part 14, it is transferred on a recording 12 in a secondary transfer part 15. Since the flexible polyamide fiber fabric is used for the intermediate transfer body 31, the contact of the image holding body 1 with the recording body 12 is excellent and the transfer efficiency is improved. The rubber of the layer 34 does not exude to the inside of the base material 32, so that the twist of the meandering of the belt is corrected and the adhesion thereof with the layer 33 becomes excellent.
