In addition to the transmission efficiency of the driven gear, the driven gear is an important medium in the step of power supply. The driven gear is connected to a metal shaft, and the driven gear is attached with a copper piece. The metal shaft simultaneously contacts the inner circumference of the copper piece, and the outer circumference of the copper piece contacts the photosensitive drum. When the metal shaft receives external power transmission, the metal shaft is electrically contacted with the copper sheet, and the copper sheet is electrically contacted with the photosensitive drum to further complete the step of discharging electricity. The photosensitive drum currently in use can be changed to have conductive characteristics and to have insulating properties. In order to provide the photosensitive drum with such characteristics, the coating layer on the photosensitive drum appears to be quite important, and the coating layer on the photosensitive drum is not allowed to have impurities, uneven thickness, and the like. Therefore, the process requirements of the photosensitive drum are extremely strict, and the cost of such a coating method is high. Furthermore, since the photosensitive drum must repeat the loop of the six steps of the aforementioned photosensitive drum operation procedure, the performance of the photosensitive drum may decrease after the photosensitive drum is used for a period of time, which may be due to a decrease in the efficiency of the electrical discharge, or The charge cannot be quickly and completely left from the photosensitive drum during exposure, so that the toner is not effective, or is not cleaned so that residual toner adheres to the photosensitive drum, etc. When the photosensitive drum cannot provide the initial working effect, the photosensitive roller must be replaced with a new one. However, in the cumbersome process of the photosensitive roller, directly replacing the photosensitive roller of the new product is undoubtedly a considerable burden for the consumer. Therefore, this creation wants to eliminate or at least alleviate the problems encountered in prior art. 6 [New content] The technical problem to be solved by this creative is to provide a conductive device for the photosensitive drum in view of the lack of the prior art. The main technical means of improvement of this creation is that the conductive device has the function of controlling the magnitude of the current, and the conductive device is directly provided with the (four) impedance capability, and can avoid excessive leakage current. There are several coating layers thereon, and the coating layer belongs to a coating film mixture, which rides a uniform material f, and the coating film of the (four) layer absorbs water, and the electric resistance value becomes low, resulting in deterioration of insulation and electric leakage. The conductive device of the two electrodes provides a uniform resistance value, and the impedance is not affected by the temperature and humidity change. The device is not affected by the coating fatigue of the X photosensitive drum, and is not affected by the temperature and humidity of the Yin environment, and can improve the traditional shouting drum. Quality is not easy = tube is missing. Moreover, the conductive device can prevent the breakdown of the photosensitive drum from being attenuated by the resistance of the conductive device without a local low impedance. The conductive device of this creation does provide the printing capability that meets the requirements. The technical means of the resistor is that the resistor has a resistance W to the current, and the resistor member can be broken by a large current and can be bribed without a short circuit. (10), t creation, and the technical means to be improved is: 'The cost of the conductive device is much lower than the cost of the photosensitive drum. Even when the power storage device is worn out, the conductive device can be turned lower and lower. Print the cost of the cost. Other objects, advantages and novel features of the present invention will become apparent from the description and the accompanying drawings. σ, , , , M4〇8496 [Embodiment] f The techniques, means and functions used in the creation of this book are taken as a better example and the details are as follows. The use of patents in the United States is not limited to such a structure.

Disk _piece both - other ::: set 1 and rotate. The photosensitive drum 3 is provided with a metal shaft view, and the gold-plated drummer 3 and the conductive device, the metal shaft 301 and the sensing device 2 are electrically connected by the conductive device. = Electrical device 1 has the effect of controlling the magnitude of the current, and the conductive device 1 directly provides the appropriate impedance capability, At which is sufficient to avoid excessive leakage current. Due to the number of coating layers, the coating layer belongs to the coating composition, which is non-homogeneous, and the coating layer will absorb water, and the electrical hybridization becomes low, resulting in poor insulation and leakage. The conductive device i of the present invention provides uniform:: the impedance is not affected by the temperature and humidity changes, so that the coating of the conductive skirt is less affected by the ambient temperature and humidity, and the moon is sufficient to improve the traditional drum. °. The quality is not easy to control the lack of tube. Moreover, the conductive device i can avoid the photosensitive core (4) (4), and the resistance value of the 8 M408496 1 has no local low impedance and the large current breakdown is lost. The conductive device 1 of the present invention is indeed capable of providing a printing capability that meets the requirements.

The receiving member 10 can be tightly coupled to the inner edge of the photosensitive drum 2, and the receiving member 10' sequentially joins the first guiding member 20, the resistor member 30 and the second guiding member 40. The conductive device 1 is provided with the efficiency of the effective current transmission by the first guide member 20 and the second guide member 40, and the impedance generated by the resistor member 30 is used to further control the magnitude of current flow. Referring also to Figure 6, Figure 7, and Figure 8, a cross-sectional view of the conductive device of the present invention. The receiving member 10 is coupled to the inner edge of the photosensitive drum 2. The receiving member 10 includes a first end 101 and a second end 102.
