摘要： PROBLEM TO BE SOLVED: To provide a heating roller which has good thermal conductivity by preventing abrasion by contact of a release layer with a sliding member and is capable of maintaining a long period of detachability of a transfer material, to provide a fixing device, and to provide an image forming device.
SOLUTION: The heating roller is provided with a core metal in which crossing groove parts and projected parts surrounded by the groove parts are formed on the surface and a heat source is arranged inside, and a release layer which is formed in the groove parts other than the surface of the projected parts. Since regular concavo-convex shape is formed on the surface of the core metal, and a release layer is arranged at the portion other than the convex surface of the concavo-convex shape, abrasion by contact of the release layer with the sliding member is prevented and excellent detachability of the transfer material can be maintained over a long period.

摘要： PROBLEM TO BE SOLVED: To form a toner image having a good image quality stably in an imaging apparatus where the gap between a toner carrier and a toner flight control means is regulated by touching a gap regulating means to a toner layer on the toner carrier.
SOLUTION: The gap between a toner carrier 12 and an FPC 4 is regulated by touching a spacer 5 being sandwiched between a toner layer TL on the toner carrier 12 and the FPC 4 to the toner layer TL in the touching region CR. The spacer 5 is provided with slots 51 corresponding to respective toner passing holes 41 and since the long side of each slot 51 is set longer than the width d of the touching region CR in the carrying direction D of the toner layer TL, toner being carried directly above the toner passing hole 41 does not touch the spacer 5.

摘要： PROBLEM TO BE SOLVED: To provide an imaging apparatus in which a toner image having a good image quality can be formed stably by controlling deformation of a gap regulating means at a position touching a toner layer thereby sustaining a uniform touching pressure between the toner layer and the gap regulating means.
SOLUTION: The gap GP is kept constant by providing a spacer 5 touching a toner layer TL on a developing roller 12 on an FPC 4. The spacer 5 is bonded to the FPC 4 only at the other end 59 on the side opposite to the side end part 58 touching the toner layer TL and a rod-like spacer reinforcing rib 55 extending in the widthwise direction X is provided on the surface of the spacer 5 between the other end 59 and the touching side end part 58. Consequently, the spacer 5 is hard to be bent in the X direction and deformation at the end part 59 due to waving of the FPC 4 or uneven thickness of an adhesive layer 60 does not extend to the touching side end part 58.

摘要： PROBLEM TO BE SOLVED: To form a toner image with good quality in an image forming apparatus wherein a gap between a toner carrier body and a toner flying control means is determined by bringing a gap determination means into contact with a toner layer on the toner carrier body.
SOLUTION: A spacer 5 is constituted of a material having a work function roughly the same as one of toner consisting of a toner layer TL. As a result, even when the spacer 5 contacts the toner layer TL, the electric charge hardly moves between them and a surface voltage of the toner layer TL is roughly uniform in a direction X of an axis of a developing roller 12. Thus, the toner can be conveyed to a starting position J for flying of the toner without generating turbulance of the surface voltage of the toner layer TL so that a toner image can be formed on an intermediate transfer belt 23 with good quality.

摘要翻译：要解决的问题：在图像形成装置中形成质量好的调色剂图像，其中通过使间隙确定装置与调色剂载体上的调色剂层接触来确定调色剂载体和调色剂飞行控制装置之间的间隙身体。解决方案：间隔件5由具有与调色剂层TL构成的调色剂大致相同的功函数的材料构成。结果，即使当间隔件5接触调色剂层TL时，电荷几乎不在它们之间移动，并且调色剂层TL的表面电压在显影辊12的轴线的方向X上大致均匀。因此，可以将调色剂输送到用于调色剂飞行的起始位置J，而不会产生调色剂层TL的表面电压的湍流，从而可以以高质量在中间转印带23上形成调色剂图像。

摘要： PROBLEM TO BE SOLVED: To stably form a quality toner image, in an image forming device regulating a gap between a toner carrier and a toner flying control means by making a gap regulating means abut on a toner layer on the toner carrier. SOLUTION: A spacer 5 extending overall length in the longitudinal direction X of a developing roller 12 between an FCP 4 and the developing roller 12 is inserted in a nearer side of a rotative direction D than a transit hole 41 for FCP toner. A gap GP between the developing roller 12 and the transit hole for the ECP toner is regulated in a fixed value because a part of the spacer 5 abuts on a toner layer 5 carried on the roller 12. Further, a controlling blade 14 controls a toner amount to be carried for a toner flying starting position J, or a carrying amount, to be 0.8 mg/cm or less. As a result, under the condition that a disturbance in a surface potential of the toner layer 5 due to the spacer 5 is being suppressed, the toner T is carried to the toner flying starting position J.
