Image forming device including switch switching according to whether fixing device is mounted or removed

An image forming device comprising:

• a device body having an opening;
• a cover configured to open and close the opening;
• a process member configured to form a developer image on a sheet;
• a fixing device removably mountable in the device body, the fixing device mounted in the device body being configured to fix the developer image formed on the sheet, the fixing device being removable from the device body through the opening when the cover is open;
• a power supply member configured to output power;
• a process-power supply member configured to supply process-power to the process member based on the power inputted from the power supply member;
• a controller;
• a switching member;
• and
• a switch switchable between:
• a first state in which the switch allows connection between the process-power supply member and the power supply member to allow input of the process-power to the process-power supply member from the power supply member and the switch is configured to transfer the power to the switching member;
• and
• a second state in which the switch disconnects the process-power supply member from the power supply member to interrupt input of the process-power to the process-power supply member from the power supply member and the switch is configured to interrupt input of the power into the switching member,
• wherein when the switch transfers the power to the switching member, the switching member switches between a transferring state in which the switching member transfers the power to the process-power supply member and an interrupting state in which the switching member interrupts input of the power to the process-power supply member, according to a signal from the controller,
• wherein the switch is configured to switch to the first state when the fixing device is mounted in the device body, and
• wherein the switch is configured to switch to the second state when the fixing device is removed from the device body.

An image forming device comprising:

• a device body having an opening;
• a cover configured to open and close the opening;
• a process member configured to form a developer image on a sheet;
• a fixing device removably mountable in the device body, the fixing device mounted in the device body being configured to fix the developer image formed on the sheet, the fixing device being removable from the device body through the opening when the cover is open;
• a conveyance roller configured to convey the sheet toward the process member and the fixing device;
• a motor configured to rotate the conveyance roller;
• a power supply member configured to output power;
• a motor drive member configured to rotate the motor using the power inputted from the power supply member;
• a switch switchable between:
• a first state in which the switch connects the motor drive member to the power supply member to allow input of the power to the motor drive member from the power supply member;
• and
• a second state in which the switch disconnects the motor drive member from the power supply member to interrupt input of the power to the motor drive member from the power supply member when the fixing device is removed from the device body;
• and
• a lever configured to rotate about a lever shaft between a first position and a second position, the lever including:
• a grip part;
• and a switch contact part configured to contact the switch,
• wherein when the grip part receives no external force, the lever is in the first position and the switch contact part contacts the switch to place the switch in the first state whereas when the grip part receives an external force, the lever is rotated from the first position to the second position and the switch contact part separates from the switch to allow the switch to move to the second state,
• wherein the switch is configured to switch to the first state when the fixing device is mounted in the device body, and
• wherein the switch is configured to switch to the second state when the fixing device is removed from the device body.
