摘要： An image-forming device includes a casing, a conveying path, a pair of registration rollers, and a process cartridge. The conveying path is disposed in the casing to convey a recording sheet. The pair of registration rollers is disposed on the conveying path to regulate a leading edge of the recording sheet conveyed along the conveying path. The process cartridge is detachably mounted on the casing, and includes a developer accommodating unit, a photosensitive member, and an upstream guide part. The photosensitive member is disposed on the conveying path. The upstream guide part is disposed upstream of the pair of registration rollers on the conveying path to guide the recording sheet toward the pair of registration rollers in cooperation with the conveying path. The upstream guide part is formed with a concaved part that is concaved in a direction away from the conveying path.

摘要： An image forming device including a pick-up roller, a planetary gear mechanism having an input gear, a trigger and an output gear, a lift mechanism, a cam member, a change-over member, and a stop assembly. The change-over member includes a first arm movable between a first position engaging with the trigger for transmitting rotation of the input gear to the output gear and a second position disengaging from the trigger for shutting off the transmission of rotation from the input gear to the output gear. The second arm is contactable with the cam member for moving the first arm between the first and second positions in accordance with the movement of the pickup roller. The stop assembly includes a third arm movable between a third position engageable with the output gear and a fourth position disengaging from the output gear, and a fourth arm contactable with the cam member for moving the third arm between the third and fourth positions. The cam portion has a cam profile configured to position the first arm at the second position and to position the third arm at the third position when the pressure plate is at the stopping position at a stopping phase of rotation of the cam portion, and to position the first arm at the first position after the start of rotation of the cam portion, and then to position the third arm at the fourth position, and to again position the third arm at the third position with maintaining the first position of the first arm after the temporary rotation stop phase and the rotation re-start phase, and then to position the first arm at the second position.
