摘要： A developing apparatus provided with a developer holding container (16a) which holds a mono-component developer and an electroconductive elastic development roller (16b ) which is provided inside the developer holding container in a manner enabling it to be driven to rotate. The electroconductive elastic development roller is disposed so that a portion of it is exposed from the developer holding container and contacts the image carrier. The mono-component developer is made to deposit on its rotating surface and form a mono-component developer layer. By the rotation of this, the developer is transferred to the region of contact with the image carrier. The developing apparatus includes an electroconductive leaf spring member (16c) for regulating the thickness of the mono-component developer layer of the electroconductive elastic development roller. This electroconductive leaf spring member is supported integrally at one end by a rotatable rigid support member (16d) and is made to elastically press against and contact the electroconductive elastic development roller for regulating the thickness of the mono-component developer layer of the electroconductive elastic development roller at the other end. The center of rotation of the rigid support member is substantially positioned on the tangent of the electroconductive leaf spring member and the electroconductive elastic development roller.

摘要： An image forming device supplies developing agent to developing portion for developing a latent image in devices such as those using electrophotography. A developing agent supplying body is formed of soft synthetic foam resin material imparted with conductivity, and imparted with physical properties such that a property of F, defined by F=S.multidot..rho./H, is between 72 and 114, where H is hardness, .rho. is density, and S is cell count of bubbles. Alternatively, the developing agent supplying body may be configured such that a moving speed of a developing agent supplying body at a contact surface is 1.4 to 1.7 times that of a developing agent transporting body. Both the above configurations ensure that an optimal amount of developing agent is supplied to the developing agent transporting body for transporting developing agent to the developing portion, thus allowing for good quality printing to be obtained.

摘要： A toner image transferring device has a roller formed of a conductive rubber foam material having a resistivity of more than 10.sup.7 .OMEGA.cm. In a toner image transferring process, a constant current is applied to the roller, whereby a charged toner image can be transferred to a sheet or paper at a desired toner transfer efficiency regardless of a size of the paper or sheet. To remove a toner pollution of the roller, a constant voltage having a polarity opposite to that of the charged toner is applied to the roller. The roller is constituted such that pore openings appear over a surface of the roller, whereby a residual part of a toner polluting the roller will not leave a stain on a rear surface of the sheet or paper.

摘要： An electrostatic latent image formed on a photosensitive drum is electrostatically developed with a non-magnetic type developer, and is electrostatically transferred from the drum to a paper. The developer is composed of a toner component and a resin powder component, one component of which has a polarity opposite to that of an electric charge of the other component generated by triboelectrification therebetween. In the developing process, a conductive foam rubber developing roller is used, which includes a conductive tubular foam rubber roller element, and a metal shaft inserted into a central bore thereof. The roller element has an outer thicker portion including a conductive filler dispersed therein, and an inner solid skin layer defining the central bore thereof and exhibiting an electrical resistivity considerably higher than that of the thicker portion for lack of conductive filler. Nevertheless, a sufficient electrical contact is established between the roller element and the shaft. A thin metal blade is pressed against the roller for regulating the thickness of the developer entrained thereby, and is arranged to compensate for a resilient deformation of the shaft caused when pressing the blade against the roller.
