Description

CROSS-REFERENCE TO RELATED APPLICATION This application is a continuation application of international application No. PCT/CN2022/141036, filed on Dec. 22, 2022, which claims the priority to Chinese patent application No. 202123372434.9, filed on Dec. 29, 2021, and No. 202211470376.X, filed on Nov. 23, 2022, the entirety of all of which is incorporated herein by reference. TECHNICAL FIELD The present disclosure generally relates to the field of image-forming apparatus technology and, more particularly, relates to a conductive part, a process cartridge, and a process cartridge set. BACKGROUND Printers (e.g., laser printers) are printing output devices that combine laser scanning technology and electrophotography technology. The laser printers include monochrome laser printers and color laser printers; and the laser printers include main bodies. A process cartridge is an essential structure in the laser printer. The process cartridge is installed in the main body of the laser printer. The process cartridge includes image-forming members such as a photosensitive drum, a developing roller, and a charging roller. These image-forming members are configured to form toner images. When the laser printer is operating, a voltage needs to be applied to the photosensitive drum, the developing roller and the charging roller to adsorb and transfer toner; and in order to obtain the voltage, the process cartridge needs to be electrically connected to the main body of the laser printer. In the existing technology, in order to provide the voltage to the process cartridge, a plurality of first electrical contact portions (conductive contacts) are disposed on the process cartridge, and a plurality of second electrical contact portions (conductive terminals) are disposed on the main-body side, such that each image-forming member may be electrically connected to the main body through each of the first electrical contact portions and each of the second contact portions; and the second electrical contact portions on the main-body side are formed using elastic conductive parts. Therefore, when the first electrical contact portion of the process cartridge is in contact with the second electrical contact portion of the main body, the process cartridge is subject to the elastic force of the second electrical contact portion on the main-body side. If there are more second electrical contact portions, the elastic force exerted on the process cartridge is greater, which may affect the installation stability of the process cartridge to a certain extent. In particular, the color laser printer includes a plurality of process cartridges; the photosensitive drum, the developing roller and the charging roller in each process cartridge are electrically connected to the main body respectively, and even the process cartridge chip is also electrically connected to the second electrical contact portion on the main-body side through the elastic conductive part, which may result in the need to dispose more second electrical contacts on the main body. Eventually, the elastic force generated between the process cartridge and the main body may become larger to affect the installation stability of the process cartridge, and the structure of the image-forming apparatus may also become more complex. SUMMARY One aspect of the present disclosure provides a conductive part, installed in a process cartridge. The conductive part includes an electrical receiving portion; an electrical output portion; and an electrical transfer portion, electrically connected to the electrical receiving portion, the electrical output portion and an electrical conduction portion respectively; and configured to transfer power received by the electrical receiving portion to the electrical output portion and the electrical conduction portion. When the conductive part is configured to conduct electricity to the process cartridge, the electrical receiving portion is electrically connected to a power supply at an outside of current process cartridge to receive a first voltage from the outside of current process cartridge. The electrical output portion is electrically connected to an image-forming member in current process cartridge and transfers a second voltage to the image-forming member; and the electrical conduction portion outputs a third voltage to the outside of current process cartridge. Another aspect of the present disclosure provides a process cartridge, where the process cartridge is detachably installed on a main body of an image-forming apparatus. The process cartridge includes a housing, where a developer accommodating chamber is disposed in the housing and configured to contain a developer; an image-forming member, disposed at the housing; and a conductive part, including an electrical receiving portion, an electrical transfer portion, and an electrical output portion, where the electrical transfer portion is electrically connected to the electrical receiving portion, the
