Image forming apparatus, image forming cartridge supporter, and image forming unit

An image forming apparatus comprising:

• a body frame;
• a slide frame slidably supported by the body frame so as to be pulled out from the body frame in a first direction;
• a plurality of image forming cartridges configured to be mounted on and dismounted from the slide frame in a second direction crossing the first direction;
• and
• a plurality of electrode members mounted on the slide frame and aligned so as to correspond to the image forming cartridges when mounted on the slide frame in a one-to-one fashion;
• a plurality of guide portions provided on the slide frame so as to correspond to the image forming cartridges in a one-to-one fashion, each of the guide portions configured to guide a corresponding image forming cartridge when the image forming cartridge is mounted on and dismounted from the slide frame;
• a plurality of coil supporting portions provided on the slide frame so as to correspond to the guide portions in a one-to-one fashion, each coil supporting portion provided at a lower end of the guide portion and extending in a direction perpendicular to both the first direction and the second direction,
• wherein each of the electrode members includes:
• a connection coil spring portion into which the coil supporting portion is inserted;
• a body-side contact portion positioned at one end of the connection coil spring portion, the body-side contact portion protruding towards the body frame and configured to be in contact with a body frame contact provided on the body frame so as to be electrically connected to the body frame contact;
• and
• a cartridge-side contact portion positioned at another end of the connection coil spring portion, the cartridge-side contact portion configured to protrude towards a corresponding image forming cartridge when mounted on the slide frame and configured to be in contact with an image forming cartridge contact provided on the corresponding image forming cartridge when mounted on the slide frame so as to be electrically connected to the image forming cartridge contact.
