摘要:
An image forming apparatus includes a main casing and a cartridge detachably mountable therein. The cartridge includes a photosensitive drum and a developing roller disposed to oppose each other. The main casing includes: a metal frame for supporting the cartridge; a lock member supported to the metal frame and movable about a first axis to allow or restrict movement of the photosensitive drum relative to the metal frame; and a contact-separation member supported to the metal frame and movable about a second axis to allow contact and separation of the developing roller relative to the photosensitive drum. The lock member and the contact-separation member are aligned in an orthogonal direction orthogonal to an axis of the photosensitive drum such that the first axis is not overlapped with the contact-separation member or the second axis is not overlapped with the lock member in an axial direction of the photosensitive drum.

A developing unit is to be attachable to and detachable from an image forming device main body. The developing unit is provided with a developer case, a developing roller coupled with the developer case, and a movement member coupled with the developer case. The movement member is capable of moving between a housing position where the movement member is substantially housed inside the developer case and a protruding position where the movement member protrudes beyond the developer case. The movement member is positioned at the protruding position and pushed by the image forming device main body in a predetermined direction while the developing unit is being attached to the image forming device main body.

An image reading apparatus includes a transport path that is inclined downwardly as advancing from an upstream side to a downstream side, an image reading section disposed in a middle of the transport path, a cover member that is bent to cause downward inclination of a face on the downstream side of the transport path to be larger than an inclination of a face on the upstream side, a support member having a plate form, the support member disposed on a rear face of the cover member and protruding toward the upstream side from a proximity of a position where the cover member is bent in the face on the downstream side, and a pressing member in which another end is supported by the support member to cause one end to be contactable with the image reading section, thereby pressing the transported medium against the image reading section.

A gear unit is provided with a shaft, a gear, a first shaft support member, a second shaft support member, and a stopper. The gear is supported by the shaft. The gear is capable of rotating and moving along the shaft. The first shaft support member supports one end of the shaft. The second shaft support member supports the other end of the shaft. The stopper is supported by the shaft. The stopper is disposed between the gear and the second shaft support member. The stopper is capable of moving along the shaft. The stopper is configured such that the stopper does not drop off from the shaft in a case where the stopper moves toward the other end of the shaft in a state where the second shaft support member is not supporting the other end of the shaft. The stopper makes contact with the second shaft support member in a case where the stopper moves toward the other end of the shaft in a state where the second shaft support member is supporting the other end of the shaft. The gear makes contact with the stopper in a case where the gear moves toward the other end of the shaft.

An image forming device includes an image forming arrangement including a medium passage and motor, and a temperature detecting unit. A supplying control unit allows supply of a recording medium in the medium passage responsive to an image-forming signal, and prevents supply of a recording medium in the passage responsive to a warm-up signal. A warm-up control unit controls the motor to drive, responsive to the warm-up signal, at a first speed if a detected temperature is least a first temperature, and a second speed lower than the first speed if the detected temperature detected is lower than the first temperature. An image forming control unit controls the motor to drive, responsive to the image-forming signal, at a third speed if the detected temperature is at least a second temperature, and a fourth speed lower than the third speed if the detected temperature is lower than the second temperature.
