An image forming apparatus which has a facsimile function by which it records image data received in facsimile communications and a printer function by which it records image data output from a host computer. The apparatus includes a printing mode setting device for setting the apparatus to one of a plurality of printing modes, a recording device for recording image data, a reception device for receiving facsimile image data, and a control device for causing the setting device to set the apparatus to a specific printing mode when facsimile image data received by the reception device is to be recorded, independent of any printing mode in which the apparatus has previously been set by the setting device. The plurality of printing modes include at least one of a draft mode in which image data is recorded in a thinned-out form and a high-quality mode in which recording is performed by one-direction printing. The specific mode is a two-direction recording mode.
An image forming apparatus of a type that has a facsimile function by which it records image data received in facsimile communications and a printer function by which it records image data output from a host computer, said image forming apparatus comprising:

1. Field of the Invention
The present invention relates to an image forming apparatus which functions as a printer for a computer or the like and as a facsimile apparatus.
2. Description of the Related Art
FIG. 1 is a perspective view showing an ink-jet cartridge;
FIG. 2 is a perspective view showing the recording section of an image forming apparatus to which an embodiment of the present invention is applicable;
FIG. 3 is a block diagram of the image forming apparatus of this embodiment;
Embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
FIGS. 1 and 2 show an example of the construction of an ink-jet printer suitable for the recording section of an image forming apparatus according to an embodiment of the present invention. In the drawings, symbol IJH indicates an ink-jet head (hereinafter referred to as the "recording head" or simply as the "head") of the type in which ink is emitted onto the recording paper by using a bubble generated by heat energy; symbol IJC indicates a detachable ink cartridge (hereinafter referred to as the "cartridge") formed as an integral unit with the head IJH and equipped with a tank IT for feeding ink to the head; and symbol IJRA (FIG. 2) indicates the body of an ink-jet recording apparatus.
As can be seen from the perspective view of FIG. 1, the cartridge IJC of this embodiment has a configuration in which the front end of the head IJH is slightly protruding from the front surface of the ink tank IT. This cartridge IJC is of a disposable type which is firmly supported by a carriage HC mounted on the ink jet recording apparatus body IJRA to be described below and, at the same time, detachable with respect to the carriage HC.
