1. A process cartridge, detachably installed in an image-forming apparatus main body, comprising:
a cartridge body;
a photosensitive drum, rotatably installed in the cartridge body, wherein the photosensitive drum is configured with an image-forming region having an electrostatic latent image;
a potential detection part including an electric circuit, configured to generate an electrical signal from the image-forming region;
a storage apparatus including a microcontroller unit (MCU) circuit and an electrical contact electrically connected to the microcontroller unit circuit, wherein the electrical contact is configured to be electrically connected to an electrical contact portion disposed in the image-forming apparatus main body; and
a first electrical connection part, wherein the first electrical connection part includes a transmission terminal; the transmission terminal is electrically connected to the potential detection part and configured to be electrically connected to the electrical contact portion disposed in the image-forming apparatus main body; and the transmission terminal is configured to obtain the electrical signal detected by potential detection part, and configured to transmit a processed electrical signal to the electrical contact portion when the transmission terminal is electrically connected to the electrical contact portion, wherein the processed electrical signal is generated according to the electrical signal and configured to determine whether the process cartridge meets expectation.
