摘要： PROBLEM TO BE SOLVED: To suppress the movement of a pointing device such as a mouse as much as possible by circulatively replacing an icon on which a cursor is arranged among 1st to 4th icons with the 1st to 4th icons whenever a 1st button of a pointing device is operated and scrolling an image in the direction of an arrow when a 2nd button is operated. SOLUTION: Image scroll is made controllable vertically and horizontally by using only one arrow among a scroll up arrow 7, a scroll down arrow 8, a scroll left arrow 10 and a scroll right arrow 11. When image scroll is performed by using the arrow 7, a cursor 5 is first arranged onto the arrow 7 by operating a pointing device, and when the right button of the pointing device is next clicked, a default arrow 7 is changed to the arrow 8, the arrow 10 and the arrow 11 each time click is performed one time at a time, and scroll in an every direction can be possible.

摘要： PROBLEM TO BE SOLVED: To enhance heat efficiency required for transfer and fixing. SOLUTION: Heat conducted from the surface of a primary transfer roller 3, formed of transparent material and the radiant heat of far-infrared radiation from a far-infrared lamp 7, are given to a toner image 10 on a belt-type photoreceptor 1 carried to a tangent part between the roller 3 and a backup roller 2. The surface temperature of the glass tube of the lamp 7 is set lower than the combustible temperature (240 deg.) of the vapor of liquid included in toner produced in a primary transfer stage. The radiant heat of the far-infrared radiation from the lamp 7 is given to paper 16, in a stage where the toner image 11 on the surface of the roller 3 is transferred and fixed on a paper 16.

摘要： PROBLEM TO BE SOLVED: To prevent toner particles from being stuck and deposited onto a brush roller when the toner particles attached to a developing blade are removed by the brush roller. SOLUTION: The brush roller 3 is constituted of a roller part constituted by flocking semiconductive synthetic resin fiber (resistivity value: 1×103 to 1×108 Ω.cm) such as rayon or nylon on a conductive cylinder and a shaft part made of metal, and the same voltage as developing voltage VD is applied to the roller 3 in the midst of developing operation. A reservoir 5 where the roller 3 is immersed in liquid developer in the midst of the developing operation is constituted of a plate metallic member, and the same developing voltage VD as that of the roller 3 is applied to the reservoir 5 together with a brush blade 6 made of metal and always coming in contact with the roller 3. Since the toner particles attached to a developing roller 1 by an inverse developing phenomenon in the midst of printing and removed by the developing blade 2 are electrified to be at the developing voltage VD, they are mostly separated from the roller 3 and dispersed in the liquid developer again, and the toner particles left without being separated are removed by the blade 6.

摘要： PROBLEM TO BE SOLVED: To prevent feeding failure of a sheet, delivery failure and carrying failure on a feeding roller device. SOLUTION: This feeding roller device 100 uses a roughened surface roller 150 provided against it in a contact state by being energized by a delivery roller 130. Surface roughness of the roughened surface roller 150 is higher than the same as surface roughness of the delivery roller 130, and hardness of its surface is also made higher than the same in the same way. Consequently, a surface of the delivery roller 130 is cut along a surface roughened shape of the roughened surface roller 150, and the surface roughened shape of the roughened surface roller 150 is transferred. Consequently, as friction resistance of the surface of the delivery roller 130 is never lowered, the feeding roller device 100 can prevent delivery failure. In the same way, the feeding roller device 100 can be used also for carriage of a sheet.

摘要： PROBLEM TO BE SOLVED: To improve the operation efficiency of a printing device by judging the presence/absence of paper corresponding with paper designating information which is administered, and at the same time, changing the priority order of printing data when there is no paper corresponding with the paper designating information. SOLUTION: An A4 size paper is housed in a paper feeding portion 5, a B5 size paper is housed in a paper feeding portion 6, and a B4 size paper is housed in a paper feeding portion 7. When information to show that there is no A4 size paper in the paper feeding portion 5 is outputted to a printing output portion 4 from the paper feeding portion 5, the printing output portion 4 transmits the information to a printing data control portion 3. Then, the printing data control portion 3 stops a process for printing data which is about to be processed. In addition, the printing data control portion 3 outputs a command to a standing-by printing data housing portion 2 in such a manner that the printing data of which the process has been stopped may be removed from a processing line for printing while keeping the priority order as is, and moved to a stand-by line. Also, the absence of the A4 size paper, the pending of a printing process and the replacing of printing orders due to the absence are notified to a host computer 1.
