Abstract: An image-forming apparatus includes: a main casing; a drawer movable in a first direction between a first position inside the main casing and a second position outside the main casing; process cartridges attachable to and detachable from the drawer; a controller; and a device-side terminal connected to the controller. The process cartridges are arranged in the first direction in an attached state to the drawer. Each process cartridge includes a photosensitive drum, a magnetic roller, a developing container for storing carrier, a conveying member, a toner sensor, a process memory, and a process-side terminal. The toner sensor is configured to output a detection signal corresponding to a concentration of toner in the developing container. The process-side terminal is for both outputting the detection signal of the toner sensor and outputting information about the process cartridge stored in the process memory. The device-side terminal is configured to contact the process-side terminal.

Abstract: In a reading device, a light transmissive member has a front surface on which an original is placed. A peripheral member is adjacent to the light transmissive member, and includes a back surface in which a reference hole is formed. The reference hole includes a first edge and a second edge intersecting with each other. A reading sensor faces the back surface of the light transmissive member and the back surface of the peripheral member. The controller controls the reading sensor to read a reading range including the reference hole to obtain a read image, and determines a reference position in the reading range based on the read image. The reference position is determined to an intersection between the first edge and the second edge. The controller sets a reading start position based on the reference position.

Abstract: A scanning device includes a casing holding a original document table. A facing area is provided to the casing, and a rectangular hole is formed on the facing area.
