摘要： PROBLEM TO BE SOLVED: To provide a toner bottler 20 that assures satisfactory dischargeability of the toner from an opening 23 and lessens the sticking toner to the external face of the toner bottle 20 which is in the vicinity of the opening 23, in comparison to conventional toner bottles. SOLUTION: An opening 23 is made in one end wall of the toner bottle 20 such that the diameter of the opening is smaller than that of the cylindrical main body. In addition, a projecting part 85 for lifting toner is formed in such a manner that part of the internal face of the shoulder of an end face having the opening 23 made in it is projected to the edge of the opening 23 from the internal face of the shoulder. Further, the internal face of the circular wall of the container that continues to the projecting part 85 in a circumferential direction is projected beyond the edge of the opening 23 in the direction of the center line L of the rotation of the container. Thereby, a part 86 projecting in the opening is formed. The toner bottle 20 is substantially horizontally placed on the bottle holder of a toner supply device such that the opening 23 faces a lateral direction. In this state, toner present in the lower part of the cylindrical main body can be lifted to the opening 23 by rotation of the toner bottle and discharged smoothly. COPYRIGHT: (C)2004,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To prevent moisture or the like being a material causing harm to imaging, from entering an imaging space of an imaging module. SOLUTION: The outer peripheral surface of an imaging case 12 of the imaging module 6 is coated with a coating material 21 having a water-vapor permeability of 0.7(g/m 2 /24hr) or less. Thus, even when the imaging case 12 is formed out of a material easy-to-transmit moisture, or even when a minute gap is produced on the imaging case 12, the moisture being a harmful material to imaging, can be prevented from entering the imaging space 13, and the image can be formed in high quality.

摘要： PROBLEM TO BE SOLVED: To speedily recover image quality by reducing the procedures of exchanging operation of parts which are the cause for deterioration in image quality when the image quality is deteriorated due to scarring of the surface of the outer periphery of a photoreceptor. SOLUTION: When the quality of an image which is formed on a recording medium S is deteriorated due to scarring of the surface of the outer periphery of the photoreceptor 6, the photoreceptor 6 with the scarred outer peripheral surface and a member for transfer 5 which is highly likely to be the cause for the scarring of the photoreceptor 6 are exchanged integrally as a transfer unit 25. Thus the procedure required for the exchange operation of the parts which are the cause for the deterioration in image quality is reduced and by preventing repeated deterioration of the same type, sure recovery of the image quality is achieved.

摘要： PROBLEM TO BE SOLVED: To use a photoreceptor having high wear resistance and durability and long lifetime and to enhance the quality of formed images without adding a new means within and around the photoreceptor. SOLUTION: The photoreceptor 13 having the high wear resistance and durability of about 0.05 to 0.5 μm per 100,000 revolutions in the abrasion loss of a surface layer is installed within a device body 1 and the moisture around the photoreceptor 13 in the device body 1 is removed by an air conditioning means 11. As a result, the adhesion of ionic substances and ammonium nitrate to the surface of the photoreceptor 13 is reduced and the occurrence of toner filming is reduced. Therefore, even if the photoreceptor 13 having high wear resistance and durability and long lifetime is used, the quality of the formed images can be enhanced without adding the new means of preventing the adhesion of the ionic substances and removing the deposits within and around the photoreceptor 13.

摘要： PROBLEM TO BE SOLVED: To promote the recycle of image forming units by easily estimating the evaluation of the remaining lives of the image forming units in an image forming module, whose lives are shortened by exposure to substances that cause deterioration of the units.
SOLUTION: The image forming device has a detection means 17 which detects an amount that the image forming units 13 and 14 in the image forming module 6 are exposed to substances that cause deterioration of them. When the image forming module 6 is recovered, the remaining lives of the image forming units 13 and 14 in the image forming module 6 can be estimated from the result of the detection by the detection means 17. Based upon the evaluation of the remaining lives, it can easily be determined whether the image forming units 13 and 14 can be recycled or not. Thus, the recyclability of the image forming units 13 and 14 can be improved.

摘要： PROBLEM TO BE SOLVED: To provide a blade type cleaning device having high durability and high removing ability by suppressing deviation of abutting pressure in a long-length direction of a blade while suppressing cost rise.
SOLUTION: In the cleaning device which removes residual toner on a photoreceptor drum 4 by pressing the blade 2 composed of a long-length plate-like elastic member against the photoreceptor drum 4, a flexible blade holder is used as a blade holder 1 supporting the blade, and the blade holder is pressured at many pressuring points (arrow 3) in the long-length direction of the blade. Even when the blade has waviness in the long-length direction at its abutting part on the photoreceptor drum, the blade holder is bent over the long-length direction profiling the waviness and absorbs the waviness.
