摘要： A rotary drive device includes a drive motor and drive transmission portion, which transmits a rotational drive force of the motor to a driven rotor and includes three or more drive transmission members. A high stiffness member is attached to a low-stiffness drive transmission member, which is one, lower in stiffness, of two of the drive transmission members, to increase stiffness of the low-stiffness drive transmission member. The two form a drive transmission point corresponding to a resonant point of a lowest resonance frequency among frequencies at a plurality of resonance points in frequency response characteristics derived from rotation information. One drive transmission point, which is on either a drive-transmission input side or output side, other than the drive transmission point corresponding to the resonant point of the lowest resonance frequency, of the low-stiffness drive transmission member is configured to transmit the rotational drive force through the high stiffness member.

摘要： An image forming apparatus includes a plurality of temperature-influence members, a first-point temperature acquisition unit, a second-point temperature estimation unit, and a controller. The plurality of temperature-influence members have influence on a temperature of a recording medium on which an image is formed. The first-point temperature acquisition unit is configured to detect or estimate a temperature of the recording medium at a first point. The second-point temperature estimation unit is configured to estimate a temperature of the recording medium at a second point, based on a detection result of at least one of a temperature of the recording medium at a point different from the second point and a temperature of a member or atmosphere. The controller is configured to control the plurality of temperature-influence members, based on an acquisition result from the first-point temperature acquisition unit and an estimation result from the second-point temperature estimation unit.
