Abstract
An image forming apparatus includes a casing including a first side plate and a second side plate, a cartridge, an exposure unit, a transfer unit, a fixing unit, a nip pressure change unit, a door, and a connection portion. The first side plate includes an opening portion. The connection portion is arranged so as to penetrate the opening portion, and includes a first portion and a second portion. At least a part of the second portion is arranged so as to overlap with the exposure unit when viewed in a predetermined direction, and is arranged between the first side plate and the exposure unit in the predetermined direction.
Claims15
An image forming apparatus comprising:
- a casing including a first side plate and a second side plate, the first side plate and the second side plate being aligned in a predetermined direction;
- a cartridge including an image bearing member that bears a toner image, the cartridge being attachable in the casing in a position between the first side plate and the second side plate and being detachable from the casing;
- an exposure unit arranged between the first side plate and the second side plate, the exposure unit being configured to form an electrostatic latent image on the image bearing member by exposing the image bearing member;
- a transfer unit configured to transfer the toner image borne on the image bearing member onto a sheet;
- a fixing unit including:
- a heating unit including a heater;
- and
- a pressing roller configured to form a fixing nip with the heating unit, the fixing unit being configured to fix the toner image transferred onto the sheet on the sheet by applying heat and pressure in the fixing nip;
- a nip pressure change unit configured to change a nip pressure with which the fixing unit nips the sheet in the fixing nip;
- a door configured to move to a closed position in which the door is closed with respect to the casing, and an opening position in which the door is opened with respect to the casing, the door being moved from the closed position to the opening position in a case where the cartridge is removed from the casing;
- and
- a connection portion configured to connect the door and the nip pressure change unit, the connection portion being configured to operate the nip pressure change unit such that the nip pressure is decreased in a case where the door moves from the closed position to the opening position,
- wherein the first side plate includes an opening portion,
- wherein the connection portion is arranged so as to penetrate the opening portion, and includes:
- a first portion arranged on an opposite side of the second side plate with respect to the first side plate in the predetermined direction;
- and
- a second portion arranged on a same side as the second side plate with respect to the first side plate in the predetermined direction, and
- wherein at least a part of the second portion is arranged so as to overlap with the exposure unit when viewed in the predetermined direction, and is arranged between the first side plate and the exposure unit in the predetermined direction.
