There is prepared a printing plate on which a material being hydrophilic due to light energy at a first temperature and being hydrophobic at a second temperature due to heat energy which is lower than the first temperature is provided. First, the whole surface of the printing plate is forcibly made either one of hydrophobic or hydrophilic. Next, a region having the other nature out of hydrophobic and hydrophilic is formed so as to correspond to an image to be printed. Then, ink is supplied onto the region having hydrophobic nature to conduct offset printing.

There are provided a conductive pattern material and a pattern-forming method by which a fine pattern having a high resolution and no wire breakage is obtained. The conductive pattern material is such that on a support surface a pattern-forming layer is formed which allows the formation of a hydrophilic/hydrophobic region directly bonded to the support surface due to energy imparted. Energy is imparted to the pattern-forming material in an imagewise manner to form the conductive material layer.

A conductive layer,and a photoconductive layer,are laminated on a support member,made of resin so that an electrophotographic master plate for printing is constituted. Electrode portions,electrically connected to the conductive layer,are formed on the widthwise directional side surfaces. When development is performed, the electrode portions,are brought into contact with an electrode,adjacent to the support member,so that the potential of the conductive layer,is made to be the same as the potential of the electrode,adjacent to the support member,though the electrode portions,. The developing apparatus has a structure for causing the electrode portions,to be grounded by a provided roller made of stainless steel and/or a conductive brush.
