Abstract
The present invention provides an apparatus having a part of a current detecting circuit configured to detect current to a heater in a fixing unit so that a main body of the image forming apparatus may have one configuration for 100 V and 200 V and provides an equal resolution of current detection for an apparatus for 100 V and an apparatus for 200 V.
Claims16
An image forming apparatus comprising:
- an apparatus main body to which a first fixing unit having a heater corresponding to a 100 V series commercial power supply and a second fixing unit having a heater corresponding to a 200 V series commercial power supply are exchangeably attachable,
- a current detecting unit provided in the apparatus main body, the current detecting unit detects current fed to the heater in the first fixing unit or the second fixing unit attached to the apparatus main body;
- and
- a circuit which connects the current detecting unit with a power supply path to the heater
- wherein an unfixed image formed on a recording material is fixed to the recording material with heat from a heater in the first fixing unit or the second fixing unit attached to the apparatus main body,
- wherein at least one of the first fixing unit and the second fixing unit has a part of the circuit, and
- wherein the part of the circuit provided in the at least one of the first and second fixing units is connected with the circuit provided in the apparatus main body when the at least one of the first and second fixing units having the part of the circuit is attached to the apparatus main body.

An image forming apparatus comprising:
- a fixing unit having a heater configured to generate heat with power supplied from a commercial power supply, the fixing unit being configured to fix an unfixed image formed on a recording material to the recording material with heat from the heater;
- a current detecting unit configured to detect current fed to the heater;
- an apparatus main body configured to accommodate the current detecting unit;
- and
- a circuit which connects the current detecting unit with a power supply path to the heater,
- wherein the fixing unit is attachable to the apparatus main body,
- wherein the fixing unit has a part of the circuit, and
- wherein the part of the circuit provided in the fixing unit is connected with the circuit provided in the apparatus main body when the fixing unit is attached to the apparatus main body.
