Image forming apparatus having a drawer unit with a paper-feeding conveying path therein

An image forming apparatus comprising:

• a drawer unit configured to include therein a paper-feeding conveying path for conveying a recording medium conveyed from a paper feeding unit on which the recording mediums are stacked to an image forming unit and/or a discharge conveying path for conveying the recording medium on which an image has been formed to a discharging unit, and be capably drawn out from an apparatus main body;
• a lock unit configured to lock the drawer unit to the apparatus main body,
• a straddle detecting unit configured to detect whether or not the recording medium straddles a conveying path in the apparatus main body and a conveying path in the drawer unit;
• and
• a controller configured to control the lock unit to lock the drawer unit to the apparatus main body when the straddle detecting unit detects the straddle, wherein the drawer unit includes a notification unit configured to notify the user of a place on the conveying path in the drawer unit at which the recording medium is jammed when the user draws out the drawer unit, and a wiring member configured to electrically connect an inner portion of the apparatus main body and the drawer unit in a state where the drawer unit is drawn out from the apparatus main body.

• and
• a controller configured to control the lock unit to lock the drawer unit to the apparatus main body when the straddle detecting unit detects the straddle, wherein
• the drawer unit includes:
• a transfer unit configured to include a transfer member that abuts against an image carrier of the image forming unit and a contact/separation mechanism that causes the transfer member to make contact with and be separated from the image carrier, and transfer an image on the image carrier onto the recording medium;
• and
• a driving unit configured to include at least a driving source to drive the lock unit and the contact/separation mechanism, and wherein
• the contact/separation mechanism is configured to be driven such that the transfer member is made into a separated state from an abutting state with respect to the image carrier when the lock unit is driven to be in the unlocking state from the locking state.
